    In an adiabatic expansion of an ideal gas [KCET (Med.) 2001; MH CET 2000]

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

    B)                 \[W=\Delta E\]

    C)                 \[\Delta E=0\]   

    D)                 \[W=0\]

    Correct Answer: B

    Solution :

              \[q=\Delta E-W\]if \[q=0\]for adiabatic process, than \[\Delta E=W\].
