What are the kinetic energy ratios within a heated substance? Translational, Rotational. Intermolecular?

Question

How would I go about finding the ratios between these 3 different types of Kinetic energy--

Rotational
Translational
Intermolecular

I'm sure it has to do with the moment of inertia, mass and molecular bond, but only being through Chem112 i am not sure where to start. I am just looking for the 5% ballpark. Are there any assumptions I need to make.

Anything helps, Thanks a Bunch

Answer 1

Each degree of freedom of a substance takes a net (1/2)kT of thermal energy.

k is Boltzmann's constant, T is absolute temperature, (Kelvin).

This means the ratio is 1:1:1

This result is aptly known as the equipartition theorem.
