Diffusion vs. Effusion

Published:

Diffusionnoun

The act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion.

Effusionnoun

A liquid outpouring.

Diffusionnoun

(physics) The scattering of light by reflection from a rough surface, or by passage through a translucent medium.

Effusionnoun

(chemistry) Process of gases passing through a hole or holes considerably smaller than the mean free path of the gas molecules.

Diffusionnoun

(physics) The intermingling of the molecules of a fluid due to random thermal agitation.

Effusionnoun

An outpouring of speech or emotion.

Diffusionnoun

The spread of cultural or linguistic practices, or social institutions, in one or more communities.

Effusionnoun

(medicine) the seeping of fluid into a body cavity; the fluid itself.

Diffusionnoun

Exchange of airborne media between regions in space in an apparently random motion of a small scale.

Effusionnoun

The act of pouring out; as, effusion of water, of blood, of grace, of words, and the like.

‘To save the effusion of my people's blood.’;

Diffusionnoun

The movement of water vapor from regions of high concentration (high water vapor pressure) toward regions of lower concentration.

Effusionnoun

That which is poured out, literally or figuratively.

‘Wash me with that precious effusion, and I shall be whiter than sow.’; ‘The light effusions of a heedless boy.’;

Diffusionnoun

The act of diffusing, or the state of being diffused; a spreading; extension; dissemination; circulation; dispersion.

‘A diffusion of knowledge which has undermined superstition.’;

Effusionnoun

The escape of a fluid out of its natural vessel, either by rupture of the vessel, or by exudation through its walls. It may pass into the substance of an organ, or issue upon a free surface.

Diffusionnoun

The act of passing by osmosis through animal membranes, as in the distribution of poisons, gases, etc., through the body. Unlike absorption, diffusion may go on after death, that is, after the blood ceases to circulate.

Effusionnoun

an unrestrained expression of emotion

Diffusionnoun

(physics) the process of diffusing; the intermingling of molecules in gases and liquids as a result of random thermal agitation

Effusionnoun

flow under pressure

ADVERTISEMENT

Diffusionnoun

the spread of social institutions (and myths and skills) from one society to another

Effusion

In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. Such a hole is often described as a pinhole and the escape of the gas is due to the pressure difference between the container and the exterior.

Diffusionnoun

the property of being diffused or dispersed

Diffusionnoun

the act of dispersing or diffusing something;

‘the dispersion of the troops’; ‘the diffusion of knowledge’;

Diffusion

Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.
