Question

The average Kinetic energy of the molecule of a gas is directly proportional to the _______________.

Answer 1

The average Kinetic energy of the molecule of a gas is directly proportional to the absolute temperature.

Average kinetic energy (E):

$$\begin{gathered} \mathrm{E}=\frac{3}{2}\mathrm{KT} \\ \mathrm{E}\propto \mathrm{T} \end{gathered}$$

Thus, the average kinetic energy of a gas molecule is directly proportional to the absolute temperature of the gas.
