Since the temperature T remain constant along the path CA, P will be inversely
proportional to V along this path. Hence, as P increases, V must decrease in a nonlinear
fashion. This is represented by the curve CA in Fig.
Along the path BC, the volume V is constant. Hence the graph of P against V is a straight
line perpendicular to the V-axis. On a P − V diagram, the corresponding path is BC as
shown in Fig. For the path AB, V is directly proportional to T pressure remaining
constant. The corresponding path AB is, therefore a straight line parallel to the V-axis.
Thus the cyclic process on a P − V diagram is represented by choice (d) in Fig.
