What happens if the eggs are dipped in liquid nitrogen? Place the frozen scrotum with eggs for cryopreservation for a long time and then use it for artificial insemination.
When working with liquefied gases, you need to remember about safety.
1 breath of liquid air and everything (everything) that gets in the way of this liquefied mixture of liquid gases will be DESTROYED - teeth, tongue, larynx, esophagus and part of the stomach.
Because you are made of living cells, not plastic.
The dead weaves will burst in about 15 minutes and you will die from extensive internal bleeding.
An ambulance will not help.
Are you a fool? There can be no liquid air. Its components can be liquid ... How many morons have divorced, poor Russia, the generation of the Unified State Exam is growing up, what will happen to the country next ?!
Yes, in principle, nothing. Due to the temperature difference, liquid air does not come into contact with the hand. This is me about pouring on your hand. If you omit it, it will become hard. But not at once.
I can say about nitrogen. If you put your hand in liquid nitrogen for a short time, nothing will happen. Liquid nitrogen has a small heat capacity. From the temperature, it will begin to boil, a cushion of steam will form, which will protect the hand. But if you drink, you can get serious injuries, because the volume of the gaseous form is much larger than the liquid one. The liquid in your stomach will turn into gas. And you will either have a long belch or stomach damage. In any case, I do not advise you to try. Regarding air, the situation is approximately the same, but it should be borne in mind that the heat capacity of the composition will be different, so there is a possibility of getting a cold burn on the hand.
It is human nature to predict the unknown based on the already familiar. And in the case of liquids, this can turn against him: the most familiar liquid to us is water. But she, by the way, has very anomalous properties. So: if you stick your hand in boiling water, then a very painful burn is guaranteed. At the same time, the temperature difference (100 and, say, comfortable 20) is only 80 degrees. In the case of liquid nitrogen, this difference, albeit in the other direction, is more than 200 degrees! It would seem, what is there to think? But come on ... It's okay. He put it in - (quickly) - took it out - and a slight tingling sensation, nothing more. Cause? Abnormally huge heat capacity of water. Unlike almost all other liquids. Simply put, to significantly cool your hand, you will need a much larger volume of liquid nitrogen than to heat your hand by the same number of degrees with boiling water.
P.S. I have great respect for Tarkovsky, including for his attention to detail. The scene in Solaris is physically unrealistic, but only at first glance. Drink enough liquid oxygen to freeze your shirt? It is impossible for a person in principle. The only option is a material with a very low heat capacity (and for humans this is determined by the fact that we consist mainly of water, with all its anomalies :))) Which, by the way, Tarkovsky (and Lem) took into account - Hari was not created from the usual substances, so anything is possible ... Don't just project it onto normal people.
But the scene of the helicopter pilots freezing to a solid state in the film "The Day After Tomorrow" is a pure fake. To achieve this effect, they need to be watered with liquid helium from a hose ...
If the skin of the hand is wet (or wet), contact with liquid nitrogen and frostbite will be in a split second. The same is with the oral cavity and esophagus. Do you really need it? The liquid nitrogen weed can be pulled out with one finger.
I fig knows about putting my hand in metal. He worked in a foundry (an electrician, though) Remains of metal are poured into a special bath. So that's it. It is impossible to approach it without protecting the exposed parts of the body .. we boiled a kettle on it. You cover your muzzle with a steelmaker's hat, put on a gaiter and jump up and put the kettle on top. If the metal has just been poured, it takes 5-7 seconds to boil .. after which the kettle explodes with steam and dies .. so they waited for another hour and only then it was possible to warm the tea relatively calmly. (Seconds in 30)) what a nafig hand to put there .. a damp branch with foliage thrown into a heated electric furnace for melting metal 1700s - flashes in flight ..
And now the specialist's answer. It all depends on how long you hold your hand in liquid air (read liquid nitrogen) and how much you blow it into your esophagus. You can relatively relaxed (a second?) Lower your hand to your elbows in liquid nitrogen (77 K) and nothing bad will happen to this hand if you don't leave it there for a long time. :) Well, if you want to freeze your hand for future generations, then this will of course require a longer limb or whole body immersion.
I'm not responsible for air, but for oxygen for sure. They poured liquid oxygen on my hand, and NOTHING happened, I just need to know the technology.
Our physics teacher bought liquid oxygen for the department for experiments and entertained us, then freshmen, with various experiments with it. Among the experiments, he promised us to pour oxygen into our hands so that we would take him home (which lured the whole stream to the fifth pair).
And now the culmination of his experiments was the promised offer to pour liquid oxygen on our hands. The main condition was that he pours into the palm, directed to the floor with spread fingers, so that not a single drop lingers on the hand. At the most crucial moment, he takes a test tube with oxygen, I substitute my hand as expected, and ... Oxygen simply rolls down my hand, flows down to the floor and instantly evaporates. It looks like pouring water onto a hot frying pan.
This happened due to the large temperature difference, between the hand and the liquid a layer of evaporating oxygen formed, which was already quite acceptable temperature. An incredibly interesting experience, about 10 people then decided to put their hand under liquid oxygen and everyone remained alive and well.
Your hand or whatever you have to drink will freeze. In order for the air to become liquid, it must also be strongly cooled (liquid nitrogen + liquid oxygen)
As a person who has drunk liquid nitrogen, I declare:
The least you will get off with is a stomach upset.
At the first moment, you feel the stomach expanding and as if about to burst. The gas heats up, everything is logical. Then, if you are in shock, do not commit the act of "belching", then hello, your stomach is fuzzy and has expanded quite a lot.
Fortunately, the first happens reflexively, there is vomiting.
Further, I took a sip of juice with pulp and I felt better. The next few days, I ate only vegetables, chicken breasts and broth strictly by the clock, so as not to aggravate the situation.
After a week, my stomach no longer bothered me.
Do not drink liquid nitrogen. This is at least fraught with thermal burns to the oral cavity, larynx and stomach, as liquid gas collected in the oral cavity damages the teeth as hell.
As already mentioned, hypothermia of the tissues will not lead to anything good. All tricks with liquid nitrogen / oxygen / air are performed by professionals, do not spoil your health.
Air is a mixture of nitrogen, oxygen, carbon dioxide (and some others) in the ratio 78: 21: 0.5: (0.5). As we can see, nitrogen occupies almost 4/5 of the air volume, therefore, for simplicity, we will talk not about liquid air, but about liquid nitrogen. So, the boiling point of nitrogen is approximately –195 ° C (obviously, liquefied air would have a similar boiling point, and their difference for the human body would be insignificant, since such low temperatures would in any case cause what will be discussed below).
If you dip your hand into a liquid with such a low temperature, close to -200 ° C, intracellular and intercellular water instantly crystallizes and, since ice tends to occupy a larger volume than liquid water, it will rupture the cells from the inside and separate them apart. Of course, at first this will happen in the surface layers of the skin, but the cooling will be so significant that the process will go deeper and lead to the total death of the limb tissues. However, you will not be able to lower your hand deep enough for all this to happen, because in response to the onset of cold necrosis of the tips of the fingers and the abundant pain signaling, you will reflexively pull your hand back.
Something similar will happen if you try to drink Sip of Liquid Nitrogen: Cold vapor of boiling liquid nitrogen hitting your face, entering your nose and mouth, will make you recoil from the source of the cold reflexively. Thus, in any case, reflexes will not allow you to commit stupidity.
In addition, you can lower your hand into a container of liquid nitrogen so quickly that heat exchange simply does not have time to occur (for this, the hand must be dry). The same trick works with molten metals (only here, on the contrary, the hand should be wet). Of course, this requires remarkable skill, willpower and speed of reaction.
