How to Practise Kinetic Theory of Gases
Start with the formulas for the pressure of an ideal gas and for the rms, average and most probable speeds, including how each changes with temperature and molar mass. Questions that compare two gases at the same temperature then reduce to ratios of these speeds.
Next work through mixtures of gases, the kinetic energy per molecule and per mole, and the specific heats with degrees of freedom. Redo any question you missed after a day.
