How to live at minus 30 degrees Celsius What is it like to live at minus 20 degrees?

I haven't been to Harbin, but I caught up with the strong wind and cooled down after the snow in Chengde, Hebei Province, and it was about -20 to -10. Just wear a sweater and pants, and wear a down jacket when you go out, but your face and ears are still blown by the wind, so you don't stay outside.

There are also many people who go shopping, and it's good to get used to it.

In fact, Hangzhou is the coldest, and many of my classmates are from the Northeast, and they all say that Hangzhou is much colder than their hometown. Because this side of the south is wet and cold, and the north is dry and cold. And there is heating in the north, the room is very comfortable, and the northerners are fully armed when they go out, and they hate to show a little flesh and skin.

I have a classmate from Suihua, Heilongjiang, who actually got chilblains after coming to Hangzhou, and it was the first time he was born, and he usually wears more and thicker clothes than us in Hangzhou, hehe.

In fact, Zhejiang people are particularly hardy.

It's good to get used to it, you can also eat popsicles and ice cream on the street, the winter in Harbin has begun to get warmer, and the city doesn't feel so cold due to the large number of people and high buildings!

Actually, it's all the same! If it's not a special job, no one will stay outside for a long time, and the clothes are relatively warm, and the house is very warm, so it's okay.

Get used to it, how cool it is, and you can also have snowball fights and build snowmen.

We Harbin people also wondered, how did you southerners survive in the summer when it was so hot?

If you get used to it, it's fine, you look at those Russians in Siberia, don't they live well! Just get used to it! And there are a lot of people!

The same life, the same habit.

I'd rather be cold than hot.

How to live at minus 40 degrees. It's the same thing.

The experience of living in a place of minus 20 degrees Celsius is this: dealing with the cold, everything is not normal. The details are as follows:

1. Drink water

Living in a place of minus 20 degrees Celsius, when drinking water, he describes it like this: "You can only drink cold water, and you can't drink it at room temperature." ”

2. Reach out

Outside, if you can't stretch out your hands, the feeling of reaching out will be more painful than a knife cut, and if you stretch your hands out, it will be red and swollen after a while.

Analysis of the causes of extreme cold

In 2012, the world was generally cold, and some experts believe that it was due to the influence of the Arctic Oscillation. When the Arctic Oscillation is in a positive phase (positive state), the pressure field in the polar region and the middle and high latitudes outside the polar region forms a "high in the south and low in the north", and cold air is trapped in the polar region.

On the contrary, when the Arctic Oscillation is in a negative phase (negative state), a situation of "high in the north and low in the south" is formed, and the cold air from the polar regions spreads southward, bringing cold weather to the middle and high latitudes, causing rare cold snaps and snowstorms in Europe and eastern Asia. At the same time, the transport of water vapor over the North Atlantic to the Mediterranean Sea and the Northwest Pacific Ocean, converging with the strong cold air from the north, also contributed to the blizzard.

If it's the first time you arrive, living at minus 20 degrees will be a test, and here are a few of them:

1. Tofu for daily consumption.

There are many stalls selling tofu in the Northeast market, but these tofu are different from the tofu in the south, in the impression of southerners, the tofu is soft and very fragile, while the frozen tofu in the Northeast is as hard as a stone, so when the boss wants to cut the tofu, he has to use an axe to chop.

2. Porridge. Cook porridge for the family, but the porridge cooked at 5 o'clock in the morning will directly turn into ice cubes at 8 o'clock in the morning, and if you put another wooden stick down, you can directly use it as an eight-treasure porridge popsicle.

3. Soak instant noodles.

When you soak a bucket of instant noodles outdoors in 100 degrees boiling water, you can see the advanced special effects in the movie, and when you hold the noodles with chopsticks and wait for 1 minute, you will see that the instant noodles are suspended (frozen).

4. Electric vehicles.

The power down is very fast, the charging is slow, and the charge is not enough.

If I live in a place of minus 20 degrees, it must be very cold, my hands and feet are cold, especially my physique, if I live in such a place, my hands and feet will definitely be frozen, I will definitely not be able to go out, I must stay in the house every day, it is too cold outside, I can't adapt to this kind of life.

Living at minus 20 degrees Celsius is a particularly uncomfortable experience. Because we basically can't go out, we usually stay at home when we have nothing to do, and even if we have something to do, it will be very uncomfortable, because the weather is very cold, which will make people feel very unbearable.

Wear short sleeves in the house, and mummify when you go out.

Because of some things, I have lived in Heilongjiang for a while, and it feels so sour in winter.

It's a little better where there is heating, I don't know the cold, and sometimes I sweat even when I wear short sleeves, but when I go out, I feel like I'm going to freeze like a dog, and even if I wear more things, I shiver.

I'm especially grateful that there is heating in the north, it's not easy to live.

My friend lived in Heilongjiang in Northeast China for a semester, and he said that it was too cold there, and it was already summer on our side, and it was still spring when we bought flowers, and the season there was so abnormal that he couldn't stand it as a southerner.

Be sure to be prepared to keep warm when you go out, it will be cold outside, but the house is heated. Therefore, wearing pajamas at home and seeing the snow outside is also a very enjoyable picture. It's best not to use an Apple phone, because the Apple phone will automatically shut down and freeze after a long time when you take it out!

On snowy days, you can come out to build snowmen, roll snowballs, and have snowball fights. It's fun!

Winters are cold and long, with little spring and autumn in mind. In the winter, I usually stay at home unless I need to go out for something necessary. Because it's so cold, you need to wear a lot of clothes to protect against the cold.

You must be fully armed, otherwise it is easy to freeze your hands and feet.

Extreme cold.

Last year, I went to the Northeast to buy fungus, just in time for the cooling, the heating was on in the car, I put on all my clothes, wrapped like a zongzi, and shivered from the cold.

So it's better to live in a heated room at minus 20 degrees Celsius, so it feels better.

"Mom, let's hurry back to Hunan, right? It's really cold to stay at my brother-in-law's house, and I can't go out at all! "A few years ago, when my sister gave birth to my niece, I went with my mother to serve my sister in confinement, I went to the house, the house and the outside of the house are like a heaven and an underground, minus 20 degrees, I regretted it for two days.

We have this temperature in Harbin in winter, but there is heating in the house

Ten degrees below zero to live needs to wear a down jacket.

Scientists have found that when a person's body temperature decreases3, the body's metabolic rate can be reduced by half, and the body's oxygen consumption is only 50% of that of normal body temperature. It is estimated that if a person's body temperature can be lowered2, the life expectancy of a person may be more than doubled.

Of course, it is impossible for a person's body temperature to be lowered or raised at will, and there is no safe way to lower the body temperature, but some special exercise methods can be used to achieve the goal, such as cold baths, winter swimming, etc.

Cryogenic sleep:

The 7 to 8 hours of adequate sleep a day that is usually advocated is essentially a metabolic state in which the body temperature is at a low trough in 24 hours, which is a kind of "low temperature health care" in a broad sense.

This is not enough, for this reason, scientists have tried to develop a kind of "special cold room", which can reduce the body temperature to about 15 when sleeping at night, and the "cold room" will automatically heat up the next morning, so that the person's body temperature will gradually return to normal.

Allowing one-third of a person's life to sleep in "cold rooms" and similar low-temperature environments saves considerable "life energy" and will lay a solid foundation for prolonging life.

It's normal to have a winter of minus ten degrees, haven't you ever seen winter in the north? Like Inner Mongolia in Northeast China, it is normal for it to be minus 30 degrees Celsius when counting nine in winter. When you go out, you must wear a down jacket and thick cotton pants or something, and then you can go out less.

But there was heating in the house, and there was a car or something to go out. It's normal.

Why does it feel cold in the north when it is minus 10 degrees Celsius and not as cold as it is minus in the south? The reason for this is that there is a difference between the perceived temperature and the actual temperature.

As soon as winter comes, especially when the cold air goes south to cause a large drop in temperature, the friends in the south can't sit still, and the ridicule on the Internet about "people in the north sitting in a house as warm as spring watching the snow fall outside the house" and "people in the south shivering and freezing into ice lumps" has aroused heated discussions and resonance among many people.

If there is heating in the north of the house, if there is no heating, you have to install an air conditioner.

Sub-zero 300 degrees does not theoretically exist.

Absolute zero. The Absolute Zero)) is the lowest temperature of thermodynamics, the unit of the thermodynamic temperature scale is k (Kelvin), and absolute zero is 0k (about or.

At this temperature, the molecules of the object have no kinetic energy but still have potential energy, and the internal energy is the minimum at this point. However, absolute zero is unattainable and is only a theoretical lower limit.

The coldest shroud.

Chile. Astronomers have discovered the coldest place in the universe, and the coldest place in the universe is called the "Pull-Back Bar Nebula", where the temperature is minus 272 degrees Celsius.

It is the coldest known place in nature and is called the "Cosmic Ice Box". In fact, Bumoje's Nebula is only nearly 1 degree above absolute zero (minus).

This "heat" (because in fact we are talking about temperatures that are always above absolute zero) is the heat that has survived to this day as the origin of the universe, and in fact, it is one of the most significant and valid proofs of the theory of the great.

I thought about this question for a long time, and I came up with the idea that absolute zero merger is an extreme low temperature that cannot be reached in the material realm, and in the physical sense, it can be achieved without an absolute vacuum of matter. But there is an exact value for absolute zero, so it can be said that the temperature will objectively exist in the cosmic hidden cover without matter, otherwise where does the temperature value of the physical vacuum come from? And how can you be sure what the physical vacuum temperature is?

So if my point is true, don't say minus 300, minus n exists. It's just a realm of knowledge that cannot be spied into in the form of human existence. So for the cessation of the movement of matter, absolute zero is the limit.

-300 degrees Celsius is theoretically non-existent. Absolute zero. (the absolute zero)) is the lowest thermodynamic temperatureThermodynamic temperature scaleThe unit is k(Kelvin), absolute zero is 0k (about or.

At this temperature, the molecules of the object have no kinetic energy, but they still have a closed potential energy, and the internal energy is the minimum at this time. However, absolute zero is unattainable and is only a theoretical lower limit.

At absolute zero, the irregular thermal motion of the various components of matter is at its lowest point, while the structural state is at its highest point. This means thermal noise in the metering instrument. It is greatly reduced at low temperatures, and very faint signals can be detected, such as from distant extragalactic galaxies.

and faint radiation from various planets.

Quantum mechanics emerged at near absolute zero.

Two major effects: superconductivity, i.e. the complete loss of resistance of certain metals; and superfluidity, i.e., the complete disappearance of flow resistance in liquid helium. The temperature of 1,1000 degrees above absolute zero can be achieved by modern cryogenic experimental techniques, but absolute zero itself is still an impossible limit.
