Question

Treat nitrogen as a rigid diatomic gas and helium as monatomic. Find the ratio of the total average kinetic energy (translational plus rotational) of a nitrogen molecule to that of a helium atom at the same temperature (two decimals).

Answer:

1.67

Solution:

Nitrogen has 5 quadratic terms, (5)/(2)kT. Helium has (3)/(2)kT. Ratio $= (5) / (3) = 1.67$ .
