Question
Let ∆Wa and ∆Wb be the work done by the systems A and B, respectively, in the previous question.
Options
∆Wa > ∆Wb
∆Wa = ∆Wb
∆Wa < ∆Wb
The relation between ∆Wa and ∆Wb cannot be deduced.

Solution
∆Wa < ∆Wb
In the p-V diagram, the area under the curve w.r.t the V axis is equal to the work done by the system. Since the area under the isotherm is greater than that under the adiabat, the work done by system A is less than that done by system B. Hence, ∆Wa < ∆Wb.
