Continuously increases

Vedclass · Answer

(A) The work done by a system in a $P-V$ diagram is given by the area under the curve,$W = \int P \, dV$.As the process moves from point $A$ to point $B$,the volume $V$ is continuously increasing.Since the pressure $P$ is always positive and the change in volume $dV$ is positive throughout the process,the incremental work $dW = P \, dV$ is always positive.Therefore,the total work done by the system,which is the cumulative sum (integral) of these positive increments,must continuously increase as the system moves from $A$ to $B$.

Consider a process shown in the figure. During this process,the work done by the system:
