Explanation:
Zeroth law of thermodynamics is known as the law of thermal equilibrium.
This law states that the two systems that are in thermal equilibrium with the third system then the two systems will be in equilibrium with each other.
According to this law, if two systems A and B individually are in thermal equilibrium with third system C, then systems A and B will also be in thermal equilibrium with each other.
Thermal equilibrium is a condition where two systems in equilibrium exchange no heat energy. There is no change in temperature.
