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

    A)  \[\frac{1}{2}PV\]                            

    B)  PV

    C)  2 PV                                     

    D)  4 PV

    Correct Answer: B

    Solution :

    Work done during the cycle = area enclosed by P-V graph = area of \[\,ABCD\] \[=\,AD\times CD\] \[=(2V-V)\times (2\,P-P)\] \[=PV\]
