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. (iv)
B. (ii)
C. (iii)
D. (i)

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 themperature is constant and the gas expands and pressure decreases i.e., `p_(2)ltp_(1)` which corresponds to diagram (iii).
