    An ideal gas expands in such a manner that its pressure and volume can be related by equation \[P{{V}^{2}}=\] constant. During this process, the gas is                                                                 [UPSEAT 2002]

    A)            Heated

    B)            Cooled

    C)            Neither heated nor cooled

    D)            First heated and then cooled

    Correct Answer: B

    Solution :

               \[P{{V}^{2}}=\]constant represents adiabatic equation. So during the expansion of ideal gas internal energy of gas decreases and temperature falls.
