A hot pack provides heat energy for sore muscles. The metabolism of fats in the body provides energy. Heat is released when a piece of wood is burned.

Explanation:

An example of endothermic process is :

Heat is needed for water to boil.

Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.

Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.
