Web1 de nov. de 2013 · In 1846 and 1849 Graham published two memoirs “On the Motion of Gases” (Graham, 1846, 1849) reporting a phenomenon which he named effusion of gases into a vacuum through a thin plate, “leaving no doubt of the truth of the general law, that different gases pass through minute apertures into a vacuum in times which are as the … Web10 de ago. de 2024 · Graham’s law of diffusion and effusion. Graham’s law expresses the relationship between a gas’s rate of effusion or diffusion and its molar mass. Effusion is the movement of a gas through a tiny hole into an open chamber, whereas diffusion is the movement of a gas through a volume or second gas.
