Both 'N_2 O' and 'CO_2' have similar rates of diffusion under similar conditions of temperature and pressure. Explain.

Two differen gases 'A' and 'B' are filled in separate containers of equal capacity under the same conditions of temperature and pressure. On increasing the pressure slightly, the gas 'A' liquefies but gas B does not liquefy even on applying high pressure until it is cooled. Explain this phenomenon.

Both propane and carbon dioxide deffuse at the same rate under identical conditions of temperature and pressure. Why?
