An HCl molecule has rotational, translational and vibrational motions. If the rms velocity of HCl molecules in its gaseous phase is $\displaystyle \bar{\nu}, \mathrm{m}$ is its mass and $\displaystyle \mathrm{k}_{\mathrm{B}}$ is Boltzmann constant, then its temperature will be :
Official answer
(3)
$\displaystyle \frac{m \bar{\nu}^2}{3 \mathrm{k}_{\mathrm{B}}}$
