The graph between $P$ and $V$ below the critical temperature is:

The correct option regarding a container containing $1 \, mol$ of a gas in a $22.4 \, L$ container at $273 \, K$ is:

The compressibility factor $(Z)$ of a gas at moderate pressure is:

Which of the following represents the $Van \ der \ Waals$ equation for $n$ moles of a real gas?

The pressure $(p)$ and volume $(V)$ isotherm of a van der Waals' gas,at the temperature at which it undergoes gas to liquid transition,is correctly represented by

Statement $-1$: The compressibility factor at the critical point is the same for different gases following van der Waal's equation.
Statement $-2$: The compressibility factor is independent of pressure at the critical temperature.
