A plot of the compressibility factor $(z)$ vs $p$ is shown below for $\mathrm{H}_2, \mathrm{He}, \mathrm{N}_2, \mathrm{CO}_2$ and $\mathrm{SO}_2$. Identify the plot for $\mathrm{CO}_2$ gas.

Dipole-induced dipole interactions are present between which of the following pairs?

A gaseous mixture of 2 moles of $A, 3$ moles of $B$, 5 moles of $C$ and 10 moles of $D$ is contained is contained in a vessel. Assuming that gases are ideal and partial pressure of $C$ is 1.5 atm , the total pressure is

Gases deviate from ideal behaviour at high pressures because the gas molecules
