(a) Calculate the total rotational kinetic energy of the molecules in 1.00 mol of a diatomic gas at 300 K.
(b) Calculate the moment of inertia of an oxygen molecule (O2) for rotation about either the y- or z-axis shown in Fig. 18.18. Treat the molecule as two massive points (representing the oxygen atoms) separated by a distance of 1.21 X 10-10 m. The molar mass of oxygen atoms is 16.0 g/mol.
(c) Find the rms angular velocity of rotation of an oxygen molecule about either the y- or z-axis shown in Fig. 18.15. How does your answer compare to the angular velocity of a typical piece of rapidly rotating machinery (10,000 rev/min)?
