First Law Of Thermodynamics

Definition

The first law, also known as Law of Conservation Of Energy, states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed, it can only be transferred or changed from one form to another.
