## Homework Statement

Below about 80 K the heat capacity at constant volume for hydrogen gas (H2) is 3/2k per molecule, but at higher temperatures the heat capacity increases to 5/2k per molecule due to contributions from rotational energy states. Use these observations to estimate the distance between the hydrogen nuclei in an H2 molecule.

## Homework Equations

boltzmann distribution (possibly)

C = deltaEatom / deltaT C=specific heat capacity

## The Attempt at a Solution

I honestly do not even have an idea on where to start this problem, any help at all, or hints on where to start, or some guidance on the equations I should use will be more than appreciated. Thanks
