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. The diffusion of water to …

Atomic diffusion in semiconductors refers to the migration of atoms, including host , dopant and impurities. Diffusion occurs in all thermodynamic phases, but the

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). Diffusion . Diffusion är ett begrepp som i ljudsammanhang betyder ungefär "spridning". En diffusor är en reflekterande yta som inte ger en skarp reflex, utan sprider den återvändande ljudenergin i tiden, så att klangen i rummet ökar utan att färgning och andra bieffekter uppstår. 2019-04-10 · Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Passive diffusion is the movement of molecules across a membrane, such as a cell membrane. The movement does not require energy.

In the body fluids the molecules of water, gases, and the ions Diffusion refers to the process of particles moving from an area of high concentration to one of low concentration. The rate of this movement is a function of temperature, viscosity of the medium, and the size (mass) of the particles.

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.

A general expression is found for the Diffusion-weighted imaging (DWI) is a form of MR imaging based upon measuring the random Brownian motion of water molecules within a voxel of tissue.

It goes from regions of higher concentration to regions of lower concentration. Diffusion definition is - the state of being spread out or transmitted especially by contact : the action of diffusing. How to use diffusion in a sentence. diffusion.

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.
