SUMMARY
The discussion focuses on determining the temperatures at which vibrational contributions to the heat capacity of air, primarily composed of diatomic nitrogen (N2), become significant. Using an effective spring constant of 2.3 x 103 N/m and an effective oscillating mass of half the atomic mass, the angular frequency is calculated as ω = 1.67 x 1015 rad/s. The energy associated with this vibration is E = 1.76 x 10-19 J. The key takeaway is that understanding these parameters is essential for accurately modeling the heat capacity of air.
