The amount of oxygen and nitrogen sharply decreases with a height. It's all about the pressure difference between the upper and lower layers of the atmosphere. The upper layers are strongly pressured on the lower, therefore in the latter much more air and below its pressure. Climbers, climbing at a big height, are experiencing some difficulties.
It all depends on the height on which the person is located. If it does not exceed 1 km, the difference is almost imperceptible, and there will be no harm to the body. The height from 1 to 3 km also cannot harm a healthy person (the body easily compensates for the lack of oxygen). Patients with people, especially those who suffer asthma, should not be sent to such a dangerous journey.
At an altitude of 5 to 6 km, the body of a healthy person mobilizes all the systems and causes them to work in reinforced mode due to lack of oxygen. The prepared person copes with such a height, so there are often various research bases and observatory. Healthy sleep and proper nutrition helps the body of scientists to cope with the stressful situation.
Places located at an altitude of 7 km and above are unsuitable for people's lives. Oxygen here is so little that blood cannot fully deliver it to all organs. They begin to test oxygen starvation. A man feels fatigue, headache, the general state is worse. At an altitude of 8 km and above, a person can spend no more than 3 days.
Life in Mountain Area
The inhabitants of the mountain areas have much better health and live longer than the inhabitants of the plains. What is this explained? Oxygen in nature is a strong oxidizing agent. Any oxidizing agent in the body is more or less caused by its aging. But a person can not live. To promote health, we need a slightly smaller oxygen content in the air than on the plains.
The optimal height for a comfortable life is about 1,500 meters above sea level. The body is experiencing a small oxygen starvation, which includes all the systems in the enhanced mode. The blood circulation and lung ventilation improves, the level of hemoglobin in the blood increases.
American scientists noticed that for people living in the mountains are characterized by gentle sounds in speech. At high altitude, such sounds are much easier to pronounce, since for this you need to squeeze the air in the throat. It is easiest to do in highland areas, since the air is more damaged here than on the plains.
What is cut air? Explain to me as a fool. What a rare air is ...
- So the guys want to calm all ... Firstly, the molecules do not become less! They are simply moving away from each other ... hence it follows that the concentration of gases does not change, the volume of the gas mixture system varies! And this is due to lower pressure ... gas mixture as a spring, the stronger to squeeze, the smaller volume in the end it will occupy ... the less potential pressure, the greater the volume! With the same concentration, the larger amount of our body must ventilate more air, but since the lungs have its own maximum, and are unable to accept more, we feel ailment (hypoxia)
- now, if the air is imagined as water, then in a liter can there will be less liters and nothing will be more ... Water drops as it were to retreat from each other.
So with air - You're up on your high mountain and opa! And there is nothing to breathe))
In general, it is a low atmospheric pressure, observed at large altitudes. -
Hence the meaning of the word "cut" - air. In which the molecules are less likely. Because they are simply less there.Saw. How pumps the ball pump? It is injected into it, the air molecules are becoming more there, and since they are always chaotically move, now they hit the ball wall more often and put on it. Therefore, the pumped ball is so elastic.
Now imagine that the pump runs in the opposite direction - pumps the air. Of course, the ball is simply flat down - and that's it. But if instead of the ball we have a hard vessel - glass, metallic, then it retains the shape and size. But air (and molecules) when pumping it in it becomes really less. Here is such air and is called rarely.So the rare air is obtained artificially. But it happens in nature. Namely:
the higher the sea level rise into the mountains, the air becomes more and more rescued. Therefore, it is difficult to breathe high in the mountains, climbers even put on oxygen masks. And even higher, where airplanes fly, the air is even more rescued. And if the sealing of the aircraft is broken, passengers will die very quickly. You ask: Why are the planes take so high, if it is dangerous? Hard economic interests are forced to this: the resolved air is much less dense than below, and therefore has less resistance. So, the plane can fly with greater speed, the flight time is reduced, fuel saves.PS Is it not time to take a break from physics? . Ploy to my page (in my world), Polystai photo albums ...

First, as a fool I will not explain. I will explain how to a normal student who did not understand the topic a little.
Secondly, well done. What is wrong to write the word cut. Many people write discharge, maybe they even think that this word comes from the word "discharge".
Actually. Of course, the word is "rare".
======================================================
And how to understand then defuse the AK 47 automatic? If the word is "rare" in this? - There is such a concept - pressure. Imagine that in the piston there is a certain amount of air, the piston is delayed, and here the previous volume has doubled, and the air remained there as much as it was before. This will be hot air, as opposed to for example, for example, the pressure of excess air in the car's tires. And do not call yourself a fool, it's bad
- "And how to understand then defuse the AK 47 automatic? If in this word is based on "rarely"? "
Developed comes from the word rare.
And discharge comes from the word discharge.
May 29 is fulfilled by exactly 66 years since the first ascent to the highest mountain of the world - Everest. After many attempts of various expeditions in 1953, New Zelandes Edmund Hillary and Nepalese Sherpa Tencing Norki reached the world vertex - 8848 meters above sea level.
To date, Everest has already conquered more than nine thousand people, with more than 300 - died when climbing. Will a person unfold 150 meters before conquering tops and descend down, if another mountaineer has become bad, and is it possible to rise to Everest without oxygen - in our material.
Conquer the top or save someone else's life
Those interested to conquer the highest peak of the world every year becomes more and more. They do not scare neither the price for climbing, measured in tens of thousands of dollars (only one lifting permit costs $ 11,000, and more services guide, sherpov, overalls and equipment), no risk to health and life. At the same time, many go completely unprepared: their romance of the mountains and a blind desire to conquer the vertex, and this is the hardest survival test. For the spring season - 2019 on Everest already 10 people. According to the media, in total in the spring of this year, 20 people died - it is more than for the whole of 2018.
Of course, in extreme tourism now a lot of commerce, it is celebrated climbers with many years of experience. If the queue for the climb to Everest had to wait for years, now it is not a problem for the next season. Only on this spring, Nepal sold 381 licensed to rise. Because of what at approaches to the top of the mountain, many hours of tourists were formed, and this is at altitudes, critical for life. There are situations where oxygen ends or lack physical resources of the body for staying in such conditions, and people can no longer go, someone dies. In cases where one of the members of the group was bad, the rest arises the question: to leave it and continue the way to achieve the goal to which they prepared all their lives, or turn around and go to the descent, while maintaining the life of another person?
According to Alpinist Nikolai Totmianin, who has committed more than 200 climb (of which five rises on eight-thousandnesses and 53 lifts to seven thousandnes), in Russian groups in mining expeditions it is not customary to leave a person who cannot go further. If someone has become bad and there are big health risks, then the whole group unfolds and goes down. It happened more than once in his practice: it happened that I had to deploy the entire expedition for 150 meters to the goal (by the way, Nikolay himself rose to the top of Everest twice without an oxygen balloon).
There are such situations when it is impossible to save a person. But just to leave him and continue to move, knowing that he can die or spoil health is, according to our concepts, nonsense, is simply unacceptable. Human life is more important than any mountain.
At the same time, Totmian notes that there is something different on Everest, since there are commercial groups from different countries: "In others, for example, the Japanese does not have such principles. There everyone is aware of themselves and aware of the responsibility that he can stay there forever ". Another important point: unprofessional climbers have no sense of danger, they do not see it. And, while in the extreme situation, when little oxygen, the body is limited to any activity, including mental. "In such a situation, people take inadequate decisions, therefore, to entrust the person to continue to move or not, it is impossible. This should be done by the leader of a group or expedition," Totmynin summarizes.
Oxygen starvation
What happens to a person at such a height? Imagine that they themselves decided to conquer the vertex. Due to the fact that we get used to high atmospheric pressure, living in the city almost on the plateau (for Moscow it is an average of 156 meters above sea level), in the mountainous country, our body is experiencing stress.
All because the mountain climate is, above all, reduced atmospheric pressure and more rareered than at sea level, air. Contrary to popular belief, the amount of oxygen in the air is not changed, only its partial pressure decreases (voltage).
That is, when we inhale the rarellied air, oxygen is not absorbed as well as at low altitudes. As a result, the amount of oxygen entered into the body decreases - a person has oxygen starvation.
That is why coming to the mountains, often instead of joy from overflowing light clean air, we get headache, nausea, shortness and severe fatigue even during a short walk.
Oxygen starvation (hypoxia) - the state of oxygen starvation as the entire organism as a whole and individual organs and tissues caused by various factors: retention of respiration, painful states, low oxygen content in the atmosphere.
And the higher and the faster we rises, the harder there may be health consequences. In serious heights, the risk of developing high-rise disease arises.
What are the heights:
- up to 1500 meters - low heights (even at hard work there are no physiological changes);
- 1500-2500 meters - intermediate (physiological changes are noticeable, blood saturation with oxygen is less than 90 percent (norm), the likelihood of mountainous disease is small);
- 2500-3500 meters - large heights (mountain illness develops with a rapid rise);
- 3500-5800 meters - very large heights (the mountain disease is often developing, blood saturation with oxygen is less than 90 percent, significant hypoxemia (decrease in blood oxygen concentration under load);
- over 5800 meters - extreme heights (pronounced hypoxemia in peace, progressive deterioration, despite the maximum acclimatization, is impossible permanent on such heights).
High-rise disease - a painful state associated with oxygen starvation due to lowering the partial pressure of oxygen in the inhaled air. It occurs high in the mountains, starting from about 2000 meters and above.
On Everest without oxygen
The highest peak of the world is the dream of many climbers. The awareness of the recalculated bulb, a height of 8848 meters exciting the mind from the beginning of the last century. However, for the first time, people were on its top only in the middle of the twentieth century - on May 29, 1953, Mountain finally submitted New Zealandc Edmund Hillary and Nepalese Sherpe Tenzing North.
In the summer of 1980, a person overcame another barrier - the famous Italian climber Reinehold Massener rose to Everest without auxiliary oxygen in special cylinders who enjoyed on the ascents.
Many professional climbers, as well as doctors pay attention to the difference in the feelings of two waters - Northia and Massener, when they were on top.
According to the memoirs of Tenzing Northia, "the sun shone, and the sky - in all her life I did not see the sky blue! I looked down and learned the places, memorable in past expeditions ... From all sides there were great Himalayas around us ... I have never seen such a spectacle and never I will not see more - wild, beautiful and terrible. "
But Messiner's memories of the same top. "I go down on the snow, from fatigue heavy, like a stone ... But they do not rest here. I have been developed and devastated to the limit ... Even half an hour - and I have an end ... It's time to leave. No sense of the greatness of what is happening. For this I am too tired."
What caused such a significant difference in describing its triumphant climb of two climbers? The answer is simple - Reinehard Massener, unlike Northia and Hillary did not breathe oxygen.
Inhalation on the top of Everest will bring the brain three times less oxygen than at the sea level. That is why most climbers prefer to conquer the vertices using oxygen cylinders.
On the eight thousands (vertices above 8000 meters) there is a so-called zone of death - the height on which a person cannot be located for a long time due to cold and lack of oxygen.
Many waters point out what to do the simplest things: to tie shoes, booty water or dressing, it becomes unusually difficult.
Most of all, our brain suffers during oxygen starvation. It uses 10 times more oxygen than all other parts of the body combined. Above 7,500 meters, a person gets so little oxygen that a violation of the blood flow of the brain and his swelling can occur.
Brain edema is a pathological process manifested by excessive accumulation of fluid in the cells of the head or spinal cord and the intercellular space, an increase in the volume of the brain.
At an altitude of more than 6000 meters, the brain suffers so much that there may be temporary bouts. The slower reaction can be replaced by excitation and even inadequate behavior.
For example, the most experienced American guide and climber Scott Fisher, most likely, having received the brain swelling, at an altitude of more than 7,000 meters asked him to call him a helicopter for evacuation. Although in the normal state of any, not even a very experienced clutter knows perfectly well that helicopters do not fly in such height. This case occurred during the infamous climb on Everest in 1996, when eight climbers died during a storm on the descent.
This tragedy has gained wide fame due to the large number of dead climbers. The victims of the climb on May 11, 1996 were 8 people, including two guides. On that day, several commercial expeditions were raised to the top at the same time. Participants of such expeditions pay money guides, and those in turn provide maximum safety and household comfort to their customers on the route.
Most of the 1996 climbers were not professional climbers and highly depended on the auxiliary oxygen in the cylinders. According to various testimonies, 34 people were released at the same time on the vertex assault, which significantly tightened the rise time. As a result, the last climber rose to the top after 16:00. Critical time lift is considered to be 13:00, after this time, the guides are required to turn customers back to go down to descend while light. 20 years ago, none of the two guides gave this order on time.
Because of the late lifting, many participants have no oxygen on the descent, during which the strongest hurricane hit the mountain. As a result, after midnight, many climbers still remained on the slope of the mountain. Without oxygen and because of poor visibility, they could not find the road to the camp. Some of them alone saved a professional climber Anatoly Breuryv. Eight people died on a grief due to the supercooling and lack of oxygen.
About the mountain air and acclimatization
Nevertheless, our body can adapt to very difficult conditions, including highlands. In order to be at an altitude of more than 2500-3000 meters without serious consequences, the usual person is required from one to four days of acclimatization.
As for the heights of more than 5000 meters, it is practically impossible to adapt to them normally, so it is possible to be on them only a limited time. The body at such heights is not able to rest and restore.
Is it possible to reduce the risk to health while at the height and how to do it? As a rule, all health problems in the mountains begin due to insufficient or improper training of the body, namely lack of acclimatization.
Acclimatization is the sum of the adaptive-compensatory reactions of the body, as a result of which a good general condition is maintained, weight, normal performance and psychological state is maintained.
Many doctors and climbers believe that it is best to adapt to height, if you get the height gradually - to do a few lifts, reaching an increasing height, and then descend and relax as low as possible.
Imagine the situation: the traveler who decided to conquer Elbrus is the highest peak in Europe, begins his journey from Moscow from 156 meters above sea level. And in four days it turns out to be 5642 meters.
And although adaptation to height is laid in us genetically, such a negligent mountaineer threatens a few days of rapid heartbeat, insomnia and headaches. But the climber who will put on ascent at least a week, these problems will be minimized.
While the resident of the mountainous regions of Kabardino-Balkaria will not be at all. In the blood of the mountains from birth more erythrocytes (red blood cells), and the lungs are on average for two liters more.
How to protect yourself in the mountains when riding or hike
- Gradually gain height and avoid a sharp height difference;
- With poor well-being to reduce riding time or walk, make more stops for rest, drink warm tea;
- Due to high ultraviolet radiation, you can get a retinal burn. To avoid this in the mountains you need to use sunglasses and a headdress;
- Bananas, chocolate, muesli, cereals and nuts helps to fight oxygen starvation;
- You should not use alcoholic beverages at an altitude - they increase the dehydration of the body and exacerbate the lack of oxygen.
Another interesting and, at first glance, the obvious fact is in the mountains, the person moves much slower than on the plain. In ordinary life, we walk at a speed of about 5 kilometers per hour. This means that the distance to a kilometer is overcome by us in 12 minutes.
To climb to the top of Elbrus (5642 meters), starting its way from a height of 3,800 meters, a healthy acclimatized person will be required on average about 12 hours. That is, the speed will fall up to 130 meters per hour compared to the usual.
By comparing these numbers, it is not difficult to understand how seriously the height affects our body.

Why the higher the more cold
Even those who have never been in the mountains know another feature of mountain air - the higher the more colder. Why is it going on, because the air closer to the sun, on the contrary, should hear more.
The thing is that we feel warm not from the air, it heats up very badly, and from the surface of the earth. That is, the ray of the sun comes from above, through the air and does not heat it.
And the land or water takes this beam, quickly quickly heated and give heat up, air. Therefore, the higher from the plain we are, the less heat from the ground we get.
Inna Lobanova, Natalia Loskitnova
With removal from the earth's surface, the air density decreases. This is because the pressure in the upper layers of the atmosphere is lower than that of the Earth.
What is the connection between air pressure and its density?
Gas density is directly proportional to its pressure. The dependence of the density of air from pressure describes the Klapairone equation: for perfect gas
,where ? - air density, p. - absolute pressure, R. - Specific gas constant for dry air (287,058 J? (kg · k)), T. - Absolute temperature in Kelvin.
To calculate air density ? At a certain height above sea level h. The following formulas are used:
where
Here
p 0 - standard atmospheric pressure at sea level (101325 PA);
T 0.- standard sea temperature (288.15 K);
g. - acceleration of free fall over the surface of the Earth (9.8 m? sec 2);
L. - the temperature drop of temperature with a height, within the troposphere (0.0065 k? M);
R. - universal gas constant (8,31447 J? (Mol · k));
M. - Molar mass of dry air (0.0289644 kg? Mol).
This is understandable and intuitive: the lower layers of air are under the strongest pressure than the top.
What does reduced pressure and low air density mean? This means that such a filling air contains less molecules, including oxygen molecules. That is why it's hard to breathe hard at high altitude.
By the way ...
At 0 ° C, the mass of one cubic meter (1 m 3) of the air is:
- at the surface of the Earth - 1, 293 kilograms;
- at an altitude of 12 km - 319 grams;
- at an altitude of 40 km - 4 grams.
Do not rush to throw away empty bottles that have accumulated after the holidays, you can do one spectacular experiment with them. It will take a container with water. Nallem a little water in the bottle itself. Then we put it in the microwave for a half two minutes to bring to a boil. After carefully we get, without raising the neck up so that steam does not come out.
Lower in the container with water. If you do everything quickly, you can observe the reverse process: steam condensation and filling the bottle with water. At the beginning, nothing worked. Condensation was somewhat sluggish and uninteresting. The experimenter changed the heating time and the amount of water from the bottle, gained cold water, but it did not change the picture.
The temperature of the glass itself was the critical parameter. The more stronger it, the slower the process of steam condensation. With a small bottle, everything was completely bad ... It turned out everything only in the evening ...
This is certainly not a vacuum. But the vacuum is quite decent. And most importantly, simply and visually for understanding.

+ Mvandreymv Couples in the bottle pushed out the air when the bottle was lowered into the water she saw the water in the investigation of the formation of condensate (the pairs turned into water), some emptiness was formed. As they said in the video: "Nature does not like emptiness. "

+ Ker Arkad Couples evenly in the bottle cools, and at a certain temperature begins to condense, the water pulling accelerates the condensation process, water is even faster in the container, at a certain point all the pairs at the same time in all areas it drops to the temperature of the condensation of the caution so sharply sucks water.
kovalev Lev.
+ Ker Arkad water vapor crowded the air. When the bottle of the throat was lowered in cold water, the pairs began to condense, and almost no air in the bottle. Thus, the bottle sharply drops the pressure, and the external atmospheric pressure pushes water into the bottle.
maxim Tepluk.
There was a thought to try to achieve a good vacuum in a hermetic ass due to chemical reactions. For example, a vacuum vessel is purified by oxygen, to withdraw air from it. Then seal. And the final stage of translate the oxygen contained in the closed vessel into a solid of any oxide may be metal. For example, burn electric shock in advance with a wire spiral.
Peter Timchenko
But the driver to pull into a bottle is not as interesting, it will be much more interesting to attach a manovakummeter to the capacitance and damage the "dry" vacuum with the external cooling of the capacity and the internal condensation of vapors in the mixture.

Hurray, the first time it turned out! True when the pshik happened. I took a bottle from under the vodka joke, 0. 7l. Poured so that the lying was not poured. Heating time-3 minutes to max power.

I am delighted. My wife was already scared. Recently, the son showed how the egg in a bottle is shoved - he is 7 years old, and I tried to explain the expansion / compressibility of gases.

There will be no deep vacuum here, even close! Make sure of misleading. But interest rises from the people to such experiments.
This is already good.

Well, the water vacuum of such a depth is not enough, so that even the smoldering electric discharge in it. And in this video, it is not seen that water (this is not even finely dispersed dust of snow crystals) founts into the volume of the bottle not through the nozzle and without fine dismissal spraying of the refrigerant in the volume of the bottle, that is, not as it works in the workers Cameras of vacuum pair-breathable heat machines.

An example of the action of the Dalton Law: "The pressure of the mixture is equal to the sum of the partial pressures of the components of its components." A mixture of air-water vapor. When condensation, the partial pressure of the steam decreases, and the air remains constant. The mixture loses total pressure and occurs. A greater vacuum in a vessel can be achieved by condensed air itself, then there will be a real "supervacuum" (within the possibility of physics). The video did not carefully watched to analyze the situation itself.
Anatoly Parkhomenko
What does this mean when it rains is a vacuum? Or in this case, the pairs replaced the air and dropping into the condensate dragged the liquid behind him? Couples completely pushed the air and the pressure of the steam less than the air the pressure difference squeezes into the bottle of water! Cool!
Evgeny E.
How to warm up, so immediately and boils - i.e. A part of the water from the liquid will quickly switch to pairs, the pressure equal and "boiling" stops until the next temperature increase.
Explanation of simple boiling begins when the pressure of saturated vapor becomes equal to external pressure.
Evgeny E.
T. E. In a bottle of steam and liquid will be in thermodynamic equilibrium - how many molecules from fluid in steam will fly away, the same and arrive back. If you increase the temperature, the speed of evaporation will be greater than the speed of condensation.
If the temperature is raised slowly, then the bubbles can not be seen, since there is enough surface area to ensure the desired evaporation rate. If you raise fast, then bubbles will go - then the "boil"
ivan88587.
No exactly the air does not draw water t to the air - it is not steam, it does not condense when cooling and does not create a vacuum. The couples, heavier than air and displaces it in any boiling capacity, and then, if the container is closed, condensed into the water, forms a vacuum.

I also invented different ways to produce a vacuum, reworked the cycling pump, etc. And then I bought such a punetration http: // Lavrplus. Prom. UA / P52544665-vakuumnyj-Nasos-2RS. HTML.
True, it was worth 1200 hryvnia in 2013, and not 2700, as now. This pump creates a vacuum, for example, for water boiling experiments at a temperature of only 2 - 3 degrees. And if you need a high vacuum, as in a kinescope, you also need a turbomolecular pump, unfortunately, its price is not available to a simple mortal, about 20 thousand hryvnia.
High vacuum has become available to people only about 120 - 150 years ago. Already do not believe, such a simple and at the same time difficult to achieve substance.

Igor, you probably saw a bunch of rollers on the Internet about infinite energy (type like a network filter takes and the light bulb is always lit). How do you think like Pranki data do? All that it comes to mind is only electric magnetic induction. Somewhere nearby should be a source that creates an alternating electro-magnetic field. Is it so?

Andrey Rybin
The effect is not explained well enough, that is, what causes a vacuum on the bottle? As a result of the fact that water is heated, and air is heated with it with it, then expands and is out of the bottle?
Petrogor
+ Andrei Rybin to understand, you need to pay attention to what water pairs differs from air. Couples, when boiling water, displaces all the air from the bottle and in the bottle actually the air almost does not remain. In a bottle, only water in a gaseous state. When moving water from a gaseous state to liquid, there is a vacuum.
Top Mikhail
What I asked did not understand how it turns out and if you warm the bottle in oil to 120 "and make the same? Bashes probably. I have not woke up yet, but something it seems to me that the couples needed a hot dry surface. And on the video, you hurry to drain the water until the bottles of water smoothly rises, and when it comes to a dry surface.

Now you can make a piston steam vacuum engine. The efficiency will be much larger than that of a regular locomotive. And if the working fluid is not water, but an easy-to-carry, then you can use the natural difference in temperatures.

+ Igor Beletsky (Investigator) without offense, but you are no longer in the first comment. Write the pretext "To" separately, in the form of "what". I understand the little increasing schoolchildren, they do not know when they are written "to", and when "what" with a particle of the subjunctive rally "would".
But it seems you consider yourself a popularizer of science. Would carefully for literacy, huh?.
And thanks for the experience, clearly. Only for those who confuse "tsya" - "here", "so that" and "what" - for them it would be nice to clarify the essence of the phenomenon. And the most accessible as possible.

A trench power station is worth, for example, a billion. But if every day a couple of milliles, a person pays 2 rubles each, then it pays off. And what percentage is the solar panel? So it's not to get them cheap to sell

You can make an effective vacuum pump for pumping air in large volumes. It is necessary to carry out a thin tube from the steam generator in a solid container, coaxial valves overlap the steam supply tube and switch the capacity of the capacitance to the pumped outline. After that, the container needs to be cooled to condensation and switch the valves back. Installation is easily scaled by half the installation of a similar container with valves in antiphase.

+ Nikolai Prosonnikov in my description is not provided for any piston. Piston, cylinder, sealing rings - this is exactly what is very difficult to mined in domestic conditions. But plastic pipes, feting of any diameters and ball valves in any construction store are sold very inexpensively and easily mounted without special skills.

+ Bang Bang. I did not understand something if it's not a question, then. Why? Explain. If the question is then. Xs. It is pretty useless. I love to make the ideas, it's my hobby, but the ideas of these on the ideas do not go anywhere (for the most part), for it is no longer my hobby (for the most part.

Chet did not understand, there all the same air is during dipping the neck of the bottle into the water. But where does he turn out then? Water dissolves in water? Not clear in general.

18 grams of water in a gaseous state at atmospheric pressure occupies a volume of 22, 4 liters
So, in order to fill a half-liter steam bottle, you need about 1/3 cm cm of water. Therefore, if the steam pushed out all the air from the bottle, and immediately clog it, then the vacuum there will arise a decent.

+ Nradrus No. The maximum pressure that can be achieved is equal to the pressure of a saturated water vapor at an experiment. Even at zero Celsius it is about 600 Pascal, which is a lot for lamps.
