Effusion - Wikipedia
In medical terminology, an effusion refers to accumulation of fluid in an anatomic space, usually without loculation. Specific examples include subdural, mastoid, pericardial and pleural effusions.
Diffusion and Effusion - Chemistry LibreTexts
2023年6月13日 · Effusion is the movement of a gas through a tiny hole into a vacuum. We want to know the rate of effusion, which is how much gas moves through the hole per unit time. We assume that the gas particles don't bump into each other while they move through the hole (this means it's a narrow hole in a thin wall).
2.9: Graham's Laws of Diffusion and Effusion - Chemistry LibreTexts
Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Difference Between Effusion and Diffusion - BYJU'S
Effusion, in simple terms, is the ability of gas to travel through a small opening. Diffusion is the ability of gases to mix with each other, usually without a barrier. Effusion occurs when the size or aperture of the hole is smaller than the mean free path of the molecules.
9.4: Effusion and Diffusion of Gases - Chemistry LibreTexts
2023年8月26日 · When this process is restricted to passage of molecules through very small openings in a physical barrier, the process is called effusion. If a mixture of gases is placed in a container with porous walls, the gases effuse through the small openings in the walls.
9.6 Effusion and Diffusion of Gases – Chemistry Fundamentals
Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time.
Graham's Law of Effusion - ChemTalk
Graham’s Law of Effusion (1848) states that the effusion rate remains inversely proportional to the square root of the molar masses of the gas. As discussed previously, effusion means the rate at which gas escapes from a hole in a container.
53 9.4 Effusion and Diffusion of Gases - Open Library Publishing …
Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices. The rates of effusion of gases are inversely proportional to the square roots of their densities or to the square roots of their atoms/molecules’ masses (Graham’s law).
Effusion and Diffusion of Gases – Atoms First / OpenStax - NSCC
Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices. The rates of effusion of gases are inversely proportional to the square roots of their densities or to the square roots of their atoms/molecules’ masses (Graham’s law).
Graham's Law of Effusion - Chemistry Steps
Graham's law of effusion indicates that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
