    For which of the following processes is the entropy change zero?

    A)  Isobaric                              

    B)  Isothermal

    C)  Adiabaric                           

    D)  None of these

    Correct Answer: C

    Solution :

                    The change in entropy ie,  \[dS=\frac{heat\,absorbed\,by\,system}{absolute\,tempertaure}\] or            \[dS=\frac{dQ}{T}\] \[dQ=0\] for adiabatic process. Therefore, entropy change is zero for adiabatic process.
