    For which of the following process is the entropy charge zero?

    A)  Isobaric              

    B)  Isothermal

    C)  Adiabatic          

    D)  None of these

    Correct Answer: C

    Solution :

                    The change in entropy \[ds=\frac{heat\text{ }absorbed\text{ }by\text{ }system~}{absolute\text{ }temperature}\] \[ds=\frac{dQ}{T}\] But \[dQ=0\]for adiabatic process. Therefore, entropy change is zero for adiabatic process.
