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. Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. ion diffusion across a semipermeable membrane Diffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells.

Diffusion is a type of passive transport. There are 4 types of passive transport in total: simple diffusion, facilitated diffusion, filtration, and osmosis. (4 votes) Culture diffusion definition, the spreading out of culture, culture traits, or a cultural pattern from a central point.

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). 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.

The molecules of both gases are in constant motion and make numerous collisions with the partition. D - diffusion coefficient (usual units are cm 2 s-1). t - time. Diffusion to a target.

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.
