    In an adiabatic expansion of an ideal gas:

    A)  \[W=-\Delta E\]                              

    B) \[W=\Delta E\]

    C)  \[\Delta E=0\]                   

    D) \[W=0\]

    Correct Answer: A

    Solution :

    For an adiabatic expansion of ideal gas \[\Delta E=q-W\] The expansion is adiabatic Hence,   \[q=0\] \[\therefore \]  \[W=-\Delta E\]
