Consider `p`-`V` diagram for an ideal gas shown in figure.

Out of the following diagrams, which figure represents the `T-p` diagram ?
(i)

Options

A.
B.
C.
D.

Answer

C

Explanation

According to the question given that PV = constant
Hence, we can say that the gas is going through an isothermal process.
Clearly, from the graph that between process 1 and 2 temperature is constant and the gas expands and pressure decreases Le. `P_2 lt P_1` which corresponds to diagram (c).
