    The zeroth law of thermodynamics for three systems A, B and C in contact demands that

    A)  A and B are in thermal equilibrium

    B)  B and C are in thermal equilibrium

    C)  A and C are in thermal equilibrium

    D)  A B and C are in thermal equilibrium

    Correct Answer: A

    Solution :

    From zeroth law of thermodynamics,' if two systems A and B are separated by an adiabatic wall, are seperately and independently in thermal equilibrium with a third system C, then the systems A and. S are also in a state of thermal equilibrium with each other. .
