  • question_answer
    A given system undergoes a change in which the work done by the system equals the decrease in its internal energy. The system must have undergone an [Haryana CEE 1996; UPSEAT 2003]

    A)            Isothermal change            

    B)            Adiabatic change

    C)            Isobaric change                   

    D)            Isochoric change

    Correct Answer: B

    Solution :

                       In adiabatic change Q = constant Þ DQ = 0 So DW = ? DU (Q DQ = DU + DW)
