Oxygen (O2, with molar mass 32.0 g/mol) gas at 282 K and 1.37 atm is confined to a cubical container 12.0 cm on a side. Calculate ΔUg/Kavg, where ΔUg is the change in the gravitational potential energy of an oxygen molecule falling the height of the box and Kavg is the molecule's average translational kinetic energy.
