The temperature in the morning is MINUS 3 degrees, and the temperature at noon is 3 degrees higher than that in the morning. What is the temperature at noon?

The answer to the formula: -3+3=0, and the temperature at noon is 0 degrees Celsius.

Refers to the temperature below zero? It's zero degrees centigrade and it's very cold. In physics, the temperature of ice-water mixture is zero degrees Celsius. It was Xia Ling, a cold summer.

There is no concept of the highest temperature in classical thermodynamics, only the theoretical lowest temperature "absolute zero". ? The third law of thermodynamics points out that "absolute zero" cannot be achieved in a limited number of steps.

In statistical thermodynamics, temperature has been given a new physical concept-a thermodynamic quantity that describes the intensity property of internal energy in the system by the rate of change of system chaos (namely entropy). Thus, a new theoretical field of "thermodynamic negative temperature region" was created.
