First law of thermodynamics is also known as joules law or quantitative law.

It means net energy interactions is stored with in the body in the form of internal energy.

It is also called as law of conservation of energy.

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems.

The law of conservation of energy states that the total energy of an isolated system is constant and the energy can be transformed from one form to another, but cannot be created or destroyed.
