    An ideal gas is taken through the cycle \[A\to B\to C\to A\] as shown in figure. If the net heat supplied to the gas in the cycle is 5l, the work done by the gas in the process \[C\to A\] is:

    A)  \[-5J\]            

    B)  \[-10J\]

    C)  \[-15J\]                       

    D)  \[-20J\]

    Correct Answer: A

    Solution :

    Given,    \[{{W}_{AB}}+{{W}_{BC}}+{{W}_{CA}}=5\] \[10+0+{{W}_{CA}}=5\] (as, during BC, change volume = 0)             \[{{W}_{CA}}=-5J\]
