    An ideal gas is allowed to expand under adiabatic conditions. The zero value is of:

    A) \[\Delta T=0\]                                   

    B) \[\Delta S=0\]

    C) \[\Delta G=0\]                                  

    D) none of these

    Correct Answer: B

    Solution :

    Adiabatic is the process in which no heat exchange occurs between the system and surrounding i.e., dq = 0 as  \[\Delta S=\frac{\Delta q}{T}\Rightarrow \Delta S=0\]
