WebFick's law describes the movement of particles over time. There are a few strategies for maximizing particle movement, such as minimizing the distance the particles have to travel, using smaller molecules, increasing pressure, and increasing surface area. Fick's law can be expressed as an equation, but it is sometimes written in different forms. how do i hide my ip address when downloading

Graham

WebGraham's law states that the rate of effusion (the escape of a gas from a container) is inversely proportional to the square root of the molecular weight of the gas. This is because as molecular weight increases, there are more molecules per unit volume, which leads to increased resistance to flow. Graham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles.
