The plot that is not valid for an ideal gas where $\mathrm{P}$ is the pressure and $\mathrm{V}$ is the volume of the gas is:

An ideal gas is subjected to a cyclic change as shown in the $\mathrm{P}-\mathrm{V}$ diagram below:

The step in which the gas will cool down is along:

Two balloons, $\mathrm{A}$ and $\mathrm{B}$, containing $0.2$ mole and $0.1$ mole of helium at room temperature and $2.0 \mathrm{atm}$., respectively, are connected. When an equilibrium is established, the final pressure of $\mathrm{He}$ in the system is:

At $298 \mathrm{K}$, assuming ideal behaviour, the average kinetic energy of a deuterium molecule is:

A specific volume of ${\mathrm{H}}_2$ requires $24 \mathrm{s}$ to diffuse out of a container. The time required by an equal volume of ${\mathrm{O}}_2$ to diffuse out under identical conditions is: 

The density of acetic acid vapor at $300 \mathrm{K}$ and $1 \mathrm{atm}$ is $5 \mathrm{mg} {\mathrm{cm}}^{-3}$. The number of acetic acid molecules in the cluster that is formed in the gas phase is the closest to 

The volume vs. temperature graph of $1$ mole of an ideal gas is given below. The pressure of the gas (in $\mathrm{atm}$) at $\mathrm{X}, \mathrm{Y}$ and $\mathrm{Z}$, respectively, are

In the following compressibility factor $\left(\mathrm{Z}\right)$ vs. pressure graph at $300 \mathrm{K}$, the compressibility of ${\mathrm{CH}}_4$ at pressures $<200 \mathrm{bar}$ deviates from ideal behaviour because:
