An experiment is carried on a fixed amount of gas at different temperatures and at high pressure such that it deviates from the ideal gas behaviour. The variation of $\frac{{PV}}{{RT}}$ with $P$ is shown in the diagram. The correct variation will correspond to

Curve $A$

Curve $B$

Curve $C$

Curve $D$

Solution

At low pressure, the gas will show ideal behaviour and hence $\frac{ PV }{ RT }=$ number of moles which will remain constant.

But as pressure increases, there will be dominant interatomic forces and actual volume will be less due to finite size. Hence, B curve will be followed.
