Diffusion refers to the net movement of atoms or molecules from regions of high concentration to regions of low concentration. Molecules or atoms will move from regions of high concentration to regions of low concentration due to random particle movement, which results in a change in the concentration gradient of a sample.
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. Diffusion refers to the net movement of atoms or molecules from regions of high concentration to regions of low concentration. Molecules or atoms will move from regions of high concentration to regions of low concentration due to random particle movement, which results in a change in the concentration gradient of a sample. Diffusion & Dispersion • Diffusion is a method by which a chemical is dispersed. • Dispersion is the “spreading out” of a chemical that can be caused by different Diffusion refers to the process by which molecules intermingle as a result of their kinetic energyof random motion.

More specifically, it is the net movement of molecules or atoms from a region of 1 Mar 2021 Diffusion is the net passive movement of molecules or particles from regions of higher to regions of lower concentration. For diffusion to occur This paper presents a simple model for such processes as spin diffusion or conduction in the "impurity band." These processes involve transport in a lattice 25 Aug 2019 Diffusion is the net movement of particles from a region of their higher concentration to a region of their lower concentration down a concentration Der Begriff Wasserdampfdiffusion wird oft als Diffusion abgekürzt. 31 May 2020 Diffusion is the movement of molecules from higher to lower concentration. In osmosis, only the solvent (water) is free to move across a Diffusion is Driven By the KINETIC ENERGY (energy of motion) the molecules possess.
14 Jan 2015 Diffusion is a mass transfer phenomenon that causes the distribution of a chemical species to become more uniform in space as time passes.
Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture. Diffusion. The transport of matter from one point to another by random molecular motions.
Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, a professor of
Hence, physically, the diffusion coefficient implies that the mass of the substance diffuses through a 1 The spreading of something more widely.

4 Sep 2019 Diffusion is a form of mixing, usually where molecules disperse.

Interstitial diffusion – movement of atoms from one interstitial site to Diffusion Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. 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.
Diffusion coefficient depends on size and shape of molecule, interaction with solvent and viscosity of solvent. Diffusion over a distance The relationship below is generally valid:
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

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 osmosis, only the solvent (water) is free to move across a Diffusion is Driven By the KINETIC ENERGY (energy of motion) the molecules possess. Because of their Kinetic Energy, molecules are in Constant Motion.

Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations; the book was first published in 1962, and is now in its fifth edition (2003).
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. 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.
