Today I learned in chemistry I learned about diffusion and effusion. Diffusion is the tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout
There is another process that involves the movement of molecules in a gas. This process is called effusion. During effusion, a gas escapes through a tiny hole in its container. With effusion and diffusion, the type of particle is important. Gases of lower molar mass diffuse and effuse faster than gases of higher molar mass.
Graham’s law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of the gas’s molar mass. This law can also be applied to the diffusion of gases.
