...relative times of the effusion of gases in mass are similar to those of the molecular diffusion, but a gas is usually carried by the former kind of impulse with a velocity many thousand times as great as is demonstrable by the latter. 2. If the aperture of efflux becomes a tube, the effusion... | |
