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

Out of following diagrams(figure). Which represents the `T-P` diagram?

Options

A.
B.
C.
D.

Answer

C

Explanation

Accoring to the question given that pV-constant Hence, we can say that the gas is going through an isothermal process.
Clearly, form the graph that between process 1 and 2 temperature is constant and the gas expands and pressure decreases i.e., `P_(2)ltP_(1)` which corresponds to diagram (iii).
