Consider two processes on a system as shown in figure (26-Q4).The volumes in the initial states are the same in the two processes and the volumes in the final states are also the same. Let ΔW1 and ΔW2 be the work done by the system in the processes A and B respectively.

1.  ΔW1 > ΔW2

2.  ΔW1 = ΔW

3.  ΔW1 < ΔW2

4.  Nothing can be said about the relation between ΔW1 and ΔW

Let ΔWa and ΔWb be the work done by the systems A and B respectively in the previous question.

1.  ΔWa > ΔWb

2.  ΔWa = ΔWb

3.  ΔWa < ΔWb

4.  The relation between ΔWa and ΔWb cannot be deduced

Previous Question: Two samples A and B are initially kept in the same state. The sample A is expanded through an adiabatic process and the sample B through an isothermal process. The final volumes of the samples are the same.
