1. The problem statement, all variables and given/known data Air is mostly composed of diatomic nitrogen, N_{2}. Assume that we can model the gas as an oscillator with an effective spring constant of 2.3 x 10^{3} 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 [itex]\omega=\sqrt{\frac{\kappa}{m}}[/itex] [itex]E=\hbar\omega[/itex] [itex]K=\frac{3}{2}k_{B}T[/itex] 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.
