Find the average kinetic energy (in J) of oxygen molecules at a temperature of 321 K.
What is the rms speed (in m/s) of oxygen molecules at 19 oC? Since oxygen is a diatomic molecule, the mass of the oxygen molecule (O2) is 5.313 x 10-26 kg.
If one wished to reduce the speed of an oxygen molecule to 63 % of the value that was obtained in the problem above, what temperature (in oC just write as "C") would be required?
