- Effusion 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).

Aug 5, 2019 · When a volume of gas is released from one smaller area to another larger area with less pressure, the gas either diffuses or effuses into the container. The primary difference between diffusion and effusion is the barrier, which filters the gas as it moves between the two volumes.

Definition and Mechanism. Diffusion refers to the spontaneous movement of particles (atoms, molecules, or ions) from an area of higher concentration to an area of lower concentration. This movement occurs due to the random motion of particles, driven by the principle of entropy.

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.
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.

We can define effusion as a process by which a gas escapes through a small hole in its container into an evacuated space. Graham’s Law of Effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
In contrast, effusion is the escape of a gas from a container through a tiny opening into an evacuated space. The rate of effusion of a gas is inversely proportional to the square root of its molar mass ( Graham’s law ), a relationship that closely approximates the rate of diffusion.
