ZEROTH LAW OF THERMODYNAMICS

It states that if two thermodynamic systems A and B are in thermal equilibrium with a third system C, then system A and B are also in thermal equilibrium with each other. It is a pre-requisite for the three laws of thermodynamics. It was invented later than the three laws of thermodynamics. That is why it is called zeroth law of thermodynamics. It is a law of thermal equilibrium. Body temperature being measured by a thermometer is there only when thermometer and body are in thermal equilibrium with each other.
