The specific heats of a gas at constant volume and constant pressure are 0.038 cal  ${\text{deg}}^{\text{-1}}{\text{g}}^{\text{-1}}{\text{\hspace{0.17em}and\hspace{0.17em}0.062\hspace{0.17em}cal\hspace{0.17em}deg}}^{\text{-1}}{\text{g}}^{\text{-1}}$

The gas has such a law crtical temperature that it cannot be condensed to form a liquid above 10k.

The atomicity of the gas molecule is 2

The molar of the gas is 83 g ${\text{mol}}^{-1}$

$C_P$ for the gas is 5 cal deg ${\text{mol}}^{-1}$
