Question

If nitrogen and hydrogen are at the same temperature T , then is it possible that the Kinetic energies of Nitrogen molecule and hydrogen molecule will be different ? Justify .

Answer 1

Postulates of kinetic theory states that The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move.

KE = 3/2 KbT

so when hydrogen and oxygen are at the same temperature they will have same KE.
