    An ideal monoatomic gas is taken around the cycle ABCDA as shown in figure. The work done during the cycle is given by

    A)  8pV                                      

    B)  pV

    C)  4pV                                      

    D)  2pV

    Correct Answer: C

    Solution :

                     Work done by ideal monoatomic gas is equal to area under p-V graph. Work done = area of p-V rectangle                 \[W=Ad\times CD\]                 \[W=(3V-V)\times (3p-p)\]                 \[W=2V\times 2=4pV\]
