Absolute zero, or Celsius.
There is no place with this temperature, and it is impossible for humans to create this temperature, only infinitely close.
1) Definitions or Interpretations.
The zero degree that is defined as the thermodynamic temperature scale (absolute temperature scale) is called absolute zero.
2) Units The unit of absolute zero is 0 3° Kelvin 0 3 .
3) Note At the secondary level, for the conversion between the thermodynamic temperature scale and the Celsius temperature scale, the approximate value t(k)=t( )273 is taken. In fact, as with water ice.
The point is the standard, and the absolute zero should be lower than it, so the exact conversion relationship should be t(k)=t( ).
Absolute zero is obtained by extrapolation according to the laws followed by ideal gases. With such a method, when the temperature is lowered to, the volume of the gas will decrease to zero. If, from the point of view of molecular motion theory, the average translational kinetic energy of an ideal gas molecule is determined by the temperature t, then absolute zero can also be said to be "the temperature at which the ideal gas molecule stops moving".
Both of the above statements are just an ideal reasoning. In fact, all actual gases exhibit significant quantum properties when the temperature is approaching, and the gas has already become liquid or solid. In short, the motion of gas molecules no longer follows the thermodynamic statistical laws of classical physics.
Through a large number of experiments and theoretical deductions after quantum mechanical corrections, it is concluded that at places close to absolute zero, the kinetic energy of molecules tends to a fixed value, which is called zero energy. This shows that at absolute zero, the energy of the molecule is not zero, but has a very small value. The reason is that all particles are in the lowest state of energy possible, that is, all particles are in the ground state.
Since the three-phase point temperature of water is, absolute zero is 273 16 lower than the three-phase point temperature of water.

Summary. Hello! I'm glad to answer that low temperature is below 36 degrees.
Hello! I'm glad to answer that low temperature is below 36 degrees.
For example, human body temperature: the body temperature of the human body is relatively constant, between 36-37 degrees. Body temperature measurement measures the body's ability to produce and release heat and regulate its own temperature.
Even though the outside temperature varies greatly, the human body is able to keep its temperature within a safe range. Low temperature usually refers to the measurement of the temperature of the human body under the armpit of the chinna. When the body temperature falls below 36 degrees Celsius, it is called hypothermia.
The cause of hypothermia is that the basal metabolic rate of stupid thoughts is relatively low, which can also cause hypothermia. However, due to the individual differences between each person who is trapped, the standard body temperature of some people is lower than 36 or higher than 37, which is a normal phenomenon and there is no need to worry about the rest of the life.
When it comes to the weather, low temperatures generally range from 0 degrees to -15 degrees Celsius. Low temperature, commonly known as cold, where the local 24h cooling Zheng Heng 10 or more or 48 hours cooling 12 or more, and the minimum temperature drops to shouting Bi to do less than 5 strong cold air is called cold wave.

Summary. My dear, the low temperature is below 36 degrees.
My dear, the low temperature is below 36 degrees.
Details: The armpit temperature of the normal human body is between 36 and 37 degrees, and below 36 degrees is low. In general, hypothermia is caused by a low basal metabolic rate, but because of individual constitutions, some people's standard body temperature is below 36 degrees, and above 37 degrees is normal.
If you have a low body temperature, you need to go to the hospital for some tests to see if there are metabolic diseases, blood circulation disorders, etc. Hypothermia is a common cause of endocrine or metabolic diseases, such as hypothyroidism and adrenal insufficiency.

Hello dear<>
Low temperature refers to a cooler environment or object for the removal of lead, usually referring to a temperature range below normal temperature. 1.Normal temperature refers to the temperature range between 20 and 30 at standard atmospheric pressure.
2.Therefore, the low temperature range is the temperature range below 20. Selling this game in different fields, the definition of low temperature may be different.
3.For example, in the frozen food industry, low temperatures are usually referred to as below -18; In scientific research, cryogenic temperature can refer to -196 at the temperature of liquid nitrogen. 4.
In general, the temperature range of low, medium and medium temperature is relative and needs to be determined on a case-by-case basis. <>

Summary. Below 36.
Below 36.
There is a certain range of human body temperature, whether the temperature of the armpits, mouth or rectum is measured, the body temperature below 35 is considered hypothermia, which is an abnormal condition. Low temperature of the limbs indicates a significant drop in body temperature, and the range of body temperature fluctuations exceeds 1, and the occurrence of low temperature may be related to low ambient temperature, or it may be caused by hypothyroidism, hypoglycemic coma, systemic failure, etc. If it is found that there is a low temperature and pretend to be a relative, the patient should be sent to an environment with suitable temperature and humidity in time, and warm measures should be taken.
If it is caused by hypoglycemic coma, glucose injection, hydrocortisone injection, etc. can be used to raise blood sugar.

The temperature of the human body is relatively constant, and the body temperature of a normal person fluctuates slightly within 24 hours, and the difference is generally not more than 1 degree. In the physiological state, the body level is slightly lower in the morning and slightly higher in the afternoon. Slightly higher body temperature in women before menstruation or during pregnancy during exercise, eating, and low body temperature in older people.
A higher than normal body temperature is called fever, 37 5 38 degrees is a low fever, 38 39 degrees is a moderate fever, 39 40 degrees is a high fever, and more than 40 degrees is a super high fever.
The relatively constant temperature of the human body is one of the important conditions for maintaining the normal life activities of the human body, such as the body temperature higher than 41 degrees or lower than 25 degrees, which will seriously affect the functional activities of various systems (especially the nervous system), and even endanger the skin and harm life.
The body's heat production and heat dissipation are regulated by the nerve center, and many diseases can cause the normal regulation of body temperature to be impaired and cause changes in body temperature. The range of normal body temperature fluctuations between individuals is achievable, and the body temperature of each person at different times of the day can be buried in different degrees, with the lowest body temperature at 6 a.m. and the highest at 4 p.m. in normal people.
The average annual temperature in the Antarctic continent is minus 25 degrees. The average annual temperature in the coastal areas of Antarctica is around minus 17 20 degrees; In the inland areas, the average annual temperature is minus 40 to 50 degrees; The East Antarctic Plateau is the coldest, with an average annual temperature as low as minus 57 degrees. The lowest temperature ever observed on Earth was minus degrees Celsius in July 1983 at the Antarctic Observatory in New Zealand.
Absolute zero is a degree, i.e., 0 Kelvin. This is the lowest limit of a temperature, which can only be approached infinitely and cannot be reached!! At this temperature, the movement of the molecules will stop, so it is impossible to get any lower than this, so theoretically the lowest temperature of ice is absolute zero! >>>More

Meteorologically, 20 o'clock (Beijing) is the daily boundary, that is, from 20 o'clock today to 20 o'clock tomorrow is a day. However, the daily maximum temperature refers to the temperature from 02 o'clock to 02 o'clock, and the daily maximum temperature observation time is 02 o'clock, and the meter is adjusted after the observation data (that is, the maximum temperature table is restored), and the daily minimum temperature is the minimum temperature value within 24 hours between 14 o'clock and 14 o'clock, and the meter is adjusted after 14 o'clock observation. Usually the daily maximum temperature occurs during the day, mostly in the afternoon, and usually the minimum temperature occurs at night, mostly in the second half of the night, but there are unusual times, especially when there is an invasion of cold air or a sudden and violent rise in temperature.
