Question

If k is the Boltzmann constant, the average kinetic energy of a gas molecule at absolute temperature T is?

Answer 1

The average kinetic energy of a gas molecule is $KE=\frac{3}{2}KT$

where $K$ is Boltzmann constant

$KE=\frac{3}{2}\times 1.381\times {10}^{-23}J/K\times 273K=5.66\times {10}^{-21}J$
