Both Statement-$I$ and Statement-$II$ are correct

(C) Statement-$I$ is correct: Thermal energy promotes random motion of particles,while intermolecular forces hold them together. If thermal energy dominates,the particles move apart,leading to a gaseous state.Statement-$II$ is correct: From the ideal gas equation,$PV = nRT$. Since $n = \frac{m}{M}$,we have $PV = \frac{m}{M}RT$. Rearranging gives $P = \frac{m}{V} \times \frac{RT}{M}$,where $\frac{m}{V} = d$ (density). Thus,$P = d \times \frac{RT}{M}$. At constant temperature $(T)$ and molar mass $(M)$,$P \propto d$ or $d \propto P$.

At $298 \ K$, a flask '$A$' of unknown volume $(V)$ contains oxygen at $5 \ atm$. Another flask '$B$' of volume $2 \ L$ contains helium at $3 \ atm$. Two flasks are connected together by a small tube of zero volume. After the two gases are completely mixed, if the resulting mixture is found to have the mole fraction of oxygen as $0.2$, the volume of flask '$A$' (in $L$) is (Assume oxygen and helium as ideal gases)
