Question

Consider P-V diagram for an ideal gas shown in Fig 12.2. Out of the following diagrams (Fig. 12.3), which represents the T-P diagram?

Philoid · Accepted Answer

It is given PV= constant

which states that the process is isothermal process. From the graph, we can see that in process 1 & 2 temperature

is constant and the gas expands, while pressure decreases

i.e., P2

∴ graph (iii) represents the correct T-P graph.

option (c) is correct.
