Heat and internal energy

The relationship between heat (Heat) and internal energy is like the relationship between work and mechanical energy. Heat is a measure of the change in internal energy of an object. If thermal equilibrium has not been reached between two regions, then heat is transferred from the hotter part of them to the cooler part.

Any substance has a certain amount of internal energy, which is related to the disordered motion of the atoms and molecules that make up the substance. When two substances at different temperatures are in thermal contact, they exchange internal energy until they are at the same temperature, i.e., they reach thermal equilibrium. Here, the amount of energy transferred is equal to the amount of heat exchanged.
