MCQ 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 zeroth law of thermodynamics. It is a law of

thermal equilibrium. Body temperature measured by a

thermometer is ok only when thermometer and body are

in thermal equilibrium with each other.
