    If temperature is increased by \[1\,\,K\] at constant volume, then work done on the gas is:

    A) \[\frac{5}{2}R\]                                

    B) \[\frac{3}{2}R\]

    C)  \[zero\]                                              

    D)  \[\frac{1}{2}R\]

    Correct Answer: C

    Solution :

    Work done on a gas is given by                 \[W=P\Delta V\] where \[P\] is pressure, \[\Delta V\] the change in volume. Given\[\Delta V=0\], therefore                 \[W=P\times 0=0\]
