Emulsification of $10 \mathrm{ml}$ of oil in water produces $2.4\times {10}^{18}$ droplets. If the surfaces tension at the oil-water interface is $0.03 {\mathrm{Jm}}^{-2}$ and the area of each droplet is $12.5\times {10}^{-16} {\mathrm{m}}^2,$ the energy spent in the formation of oil droplets is:

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:

The gas that has the slowest rate of diffusion among ${\mathrm{O}}_2, {\mathrm{H}}_2, {\mathrm{CO}}_2$ and ${\mathrm{CH}}_4$ is:

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:

For an ideal gas, Boyle's law is best described by -

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
