0 degrees represent no temperature? Instrument to tell you this statement is not correct. In People's Daily life, the degree of hotness or coldness of the weather by the temperature, it is changing with the alternation of all the year round. Like a 0 degrees Celsius, it said the temperature of the ice and water are mixed together, since the 0 degrees Celsius above zero, above freezing temperature, the higher the absolute value, the more warmth; Below zero degrees Celsius below zero for minus temperature, the higher the absolute value, the more cold. While 0 degrees do not represent no temperature, but has the absolute zero, that is & ndash; — - 273. 16℃。 The beginning of the absolute zero, the absolute scale, is the limit of temperature, equivalent to - 273. 16 ℃, when the temperature is reached all atoms and molecules heat movement will be stopped. This is only an approximation, but not reach the lowest temperature. Human got zero in 1926. The low temperature of 71 k, 1933, 0. The low temperature of 27 k, created in 1957 0. 00002 k cryogenic records. At present, people have even got three thousand per from absolute zero only at low temperature, but still could not get the absolute zero. If there really is absolute zero, so can't detect? Is there a measuring instrument for temperature can be measured to the absolute zero and not interfere with the system under test ( Tested the system if the disturbance of atoms movement, thus, it is not absolute zero) ? Indeed, absolute zero out depend on calculation can't be measured, the study found that the temperature falls, the molecular activity will slow down, then rely on calculation, when to absolute zero, molecules are stationary, so it is concluded that the concept of absolute zero.
