Physics - Heat & Thermo Question with Solution | TestHub

The average kinetic energy of a molecule of the gas  $=\frac{3}{2}RT$.

Average kinetic energy of one molecule of gas $=\frac{3}{2}kT ( k=\frac{R}{N_{\mathrm{A}}})$

Where $k$ is Boltzmann constant and $T$ is absolute temperature.

So, from above relation we can say average kinetic energy of molecule is directly proportional to absolute temperature.
