    Consider two process A and B on a system as shown in the figure let \[\Delta {{W}_{1}}\] and \[\Delta {{W}_{2}}\] be the work done by the system in the process A and B respectively then:-

    A)  \[\Delta {{W}_{1}}>\Delta {{W}_{2}}\]

    B)  \[\Delta {{W}_{1}}<\Delta {{W}_{2}}\]

    C)  \[\Delta {{W}_{1}}=\Delta {{W}_{2}}\]

    D)  Nothing can be said about the relation between \[\Delta {{W}_{1}}\] and \[\Delta {{W}_{2}}\]

    Correct Answer: B

    Solution :

    dk; \[Z\Delta W=PDV\]  \[\because \] \[\Delta V\] is same \[Q\Delta W\propto r\] \[\therefore \]\[\Delta {{W}_{2}}>\Delta {{W}_{1}}\]
