52. Estimate how many times per second a collision of a molecule of oxygen gas occur with one of the walls of its con tainer, which is a cube with sides $1.0\mathrm{m}$. There are $2.0\mathrm{mol}$ of oxygen inside at $30^{-}\mathrm{C}$. [Hint Let $\overline{\mathrm{v}},-\sqrt{v_1}$.] 53. Consider a container of oxygen gas at a temperature of $20-\mathrm{C}$ that is $0.50\mathrm{m}$ tall. Compare the graviational potential energy of a molecule at the top of the container (asxuming the potential eserpy is rero at the bottom) with the average kinetic energy of the molecules. Is it reasonable to neglect the potential energy?
