diffusion definition: 1. the action of spreading in many directions: 2. (of a gas or liquid) the process of spreading…. Learn more.

Gas - Gas - Diffusion: Diffusion in dilute gases is in some ways more complex, or at least more subtle, than either viscosity or thermal conductivity. First, a mixture is necessarily involved, inasmuch as a gas diffusing through itself makes no sense physically unless the molecules are in some way distinguishable from one another. Second, diffusion measurements are rather sensitive to the

In this video, we cover:- What diffusion is- Some examples of diffusion working in our cells and blood vessels- Factors that affect the rate of diffusion 2019-06-27 · Diffusion Index: 1. A measure of the percentage of stocks that have advanced in price or are showing a positive momentum over a defined period. It is used in the technical analysis of stocks. 2.

It is used in the technical analysis of stocks. 2. A Diffusion (av latinets diffusio, av diffundere, "utbreda") är den spontana spridningsprocess som äger rum när något, oftast gaser eller vätskor, med en egenskap skilt från omgivningen sprids, blandas och jämnas ut. diffusion. diffusion (latin diffuʹsio, av diffuʹndo ’sprida (sig),’), spontan materialtransport eller utbredning av ett ämne, orsakad av slumpvisa förändringar i egenrörelserna hos ämnets atomer eller molekyler. Alla mikroskopiska partiklar befinner sig i rörelse, och när partiklarna i mediet kolliderar förändras hastigheter och riktningar slumpvis.

diffusion [dĭ-fu´zhun] 1. the state or process of being widely spread. 2. the spontaneous mixing of the molecules or ions of two or more substances resulting from random thermal motion; its rate is proportional to the concentrations of the substances and it increases with the temperature. In the body fluids the molecules of water, gases, and the ions

t - time. Diffusion to a target. For target diameter y, and diffusion distance x, the diffusion of a particle to a target depends strongly on dimension.

Abstract. Diffusion in a spatially rough one-dimensional potential is treated by analysis of the mean first passage time. A general expression is found for the

Diffusion happens in liquids and gases because their particles move randomly from place 2021-4-9 · Diffusion of a solute in a solvent is caused by a concentration gradient. Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration. … DIFFUSION OF RESPIRATORY GASES The tendency of the molecules of a substance (gas, liquid, or solid) to move from a region of high concentration to one of lower concentration. In the body, oxygen and carbon dioxide move by diffusion.

Consider two containers of gas A and B separated by a partition. The molecules of both gases are in constant motion and make numerous collisions with the partition. The value for f calculated for a sphere is a minimal value; asymmetric shape of molecule or non-elastic interaction with solvent (e.g. hydration) will increase f. Diffusion coefficient depends on size and shape of molecule, interaction with solvent and viscosity of solvent.
