Is the word "hot" interpreted by China tradition?

(1) Weather heat means high temperature, and "heat" here means "temperature";

(2) Friction generates heat, which means that when an object does work on friction, the temperature rises and the internal energy increases. Here, "heat" means "internal energy".

(3) The heat absorption of an object means that the object absorbs heat from the outside. Here, "hot" means "hot";

So the answer is: temperature; Internal energy; Heat.
