Definition of heat

Heat means that when the change of system state comes from the destruction of thermal balance conditions, that is, from the temperature difference between the system and the outside world, we say that there is thermal interaction between the system and the outside world. As a result, energy is transferred from a high-temperature object to a low-temperature object, and the transferred energy is called heat. Heat is energy and everything works as energy. The conservation of energy will not disappear, nor will it happen out of thin air, but it can only be transformed from one form of energy to another.
