  • The behaviour of gases has been expressed in terms of various gas laws obtained experimentally i.e Boyle's law , Charles law , Pressure-temperature law , Dalton's law of partial pressure , Graham's law of diffusion and Avogadro's hypothesis . Later on Maxwell derived kinetic equation $PV = \large\frac{1}{3}mnu^2$ , theoretically by assuming the concept of molecules and their motion . The term u represents root mean square speed of molecule.
$U_{rms} = \sqrt{\large\frac{3RT}{m}} = \sqrt{\large\frac{3\times8.314\times300}{64\times10^{-3}}}$
$= 3.42 \times 10^2 m/S$
Hence answer is (A)
