    Which of the following is correct option for free expansion of an ideal gas under adiabatic condition?

    A) \[q=0,\Delta T<0,W\ne 0\]

    B) \[q=0,\Delta T\ne 0,W=0\]

    C) \[q\ne 0,\Delta T=0,W=0\]

    D) \[q=0,\Delta T=0,W=0\]

    Correct Answer: D

    Solution :

    [d] For adiabatic condition q=0 For free expansion, w = 0 \[\Delta E=q+w\] So \[\Delta E=0\] & internal energy depends on temperature.
