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

    A)  Isobaric              

    B)                                         Isothermal        

    C)                         Adiabatic                           

    D)                         None of these

    Correct Answer: C

    Solution :

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