Gra·ham law (grā'ăm), the relative rapidity of diffusion of two gases varies inversely as the square root of their densities, that is, their molecular weights. [Thomas Graham] Gra·ham law (grā'ăm law) The relative rapidity of diffusion of two gases varies inversely as the square root of their densities, i.e., their molecular weights. [Thomas Graham]Graham law (grā′ăm) [Thomas Graham, Brit. chemist, 1805–1869] A law stating that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass (molecular weight).Graham, Thomas, English chemist, 1805-1869. Graham law - the relative rapidity of diffusion of two gases varies inversely as the square root of their densities, i.e., their molecular weights. |
