Three sample, A,B,C of a gas initially have the same volume. The volume of each sample is doubled by the following processes: (i) isothermal process on A, (ii) adiabatic process on B, and (iii) isobaric process on C. In which process will the work done be highest?

Explanation

The processes on the three sample are shown on a pV diagram( fig). Two vertical lines X and Y denote the volume V and 2V. In this diagram, the area under a curve represents the work done. Clearly, this area is the largest for the isobaric process on sample C. So the work done in this process will be the highest.
