    Four curves A, B, C and D are drawn in the adjoining figure for a given amount of gas. The curves which represent adiabatic and isothermal changes are [CPMT 1986; UPSEAT 1999]

    A)            C and D respectively

    B)            D and C respectively

    C)            A and B respectively

    D)            B and A respectively

    Correct Answer: C

    Solution :

                       As we know that slope of isothermal and adiabatic curves are always negative and slope of adiabatic curve is always greater than that of isothermal curve Hence in the given graph curve A and B represents adiabatic and isothermal changes respectively.
