Are internal energy and heat energy ...

Are internal energy and heat energy the same ? Exaplain .

Text Solution

Verified by Experts

Internal energy and thermal energy do not mean the same thing, but they are related. Internal energy is the energy stored in a body. It increases when the temperature of the body rises, or when the body changes from solid to liquid or from liquid to gas.
..Heat is the energy transferred from one body to another as a result of a temperature difference...
