1.State Law of Equipartition of Energy and find total internal energy of 1 mole of monoatomic and diatomic gases.
2.Write expression for rms speed $v_{rms} = \sqrt{\frac{3RT}{M}}$ and average kinetic energy per molecule $E = \frac{3}{2} k_B T$.
3.Define mean free path $\lambda$ of gas molecules and write its expression $\lambda = \frac{1}{\sqrt{2} n \pi d^2}$.
