Which of the following graphs between pressure ' p ' versus volume ' V ' represents the maximum work done?

Step-by-step solution

In a pressure-volume ( P-V ) graph, the magnitude of work done is represented by the area under the curve bounded by the volume axis. Let's analyze the area under the curve for each graph: Graph (1) represents an expansion from V = 22.4 L to V = 44.8 L. The area is the integral _ 22.4 ^ 44.8 P dV , which covers a significant region under the curve. Graph (2) represents a cyclic process. The net work done is the area enclosed by the loop. This area is much smaller than the total area under the expansion curve in gra
