Thermal Behavior of Air
1. The problem statement, all variables and given/known data

Air is mostly composed of diatomic nitrogen, N2. Assume that we can model the gas as an oscillator with an effective spring constant of 2.3 x 103 N/m and and effective oscillating mass of half the atomic mass. For what temperatures should vibration contribute to the heat capacity of air?

2. Relevant equations


3. The attempt at a solution

[itex]\omega=\sqrt{\frac{\kappa}{m}}=1.67\times10^{15} rad/s[/itex]
[itex]E=\hbar\omega=1.76\times10^{-19} J[/itex]

I am not sure what to do next.
