    Consider the following two statements and choose the correct answer. (a) If heat is added to a system its temperature must always increase. (b) If positive work is done by a system in thermodynamic process, its volume must increase.

    A)  Both (a) and (b) are correct

    B) (A) is correct, but (B) is wrong

    C)  (B) is correct, but (A) is wrong

    D)  Both (A) and (B) are wrong

    Correct Answer: C

    Solution :

    In cyclic and isothermal process energy supplied to a system does not change temperature of the system. If gas expands\[(\Delta W=\pm ve)\], then volume of gas system increases. Hence, option C is true.
