Question

Temperature of gas is a measure of :

• A. the average translational kinetic energy of the gas molecules
• B. the average potential energy of the gas molecules
• C. the average distance of the gas molecules
• D. the size of the molecules of the gas

Answer 1

The correct option is A the average translational kinetic energy of the gas molecules

Temperature is a measure of average translational kinetic energy of molecules expressed as:

$K{E}_{avg}=\frac{3}{2}{k}_{B}T$, where $k_B$ is the Boltzmann constant
