Diffusion - Wikipedia Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration Diffusion is driven by a gradient in Gibbs free energy or chemical potential
Diffusion - Definition, Examples and Types | Biology Dictionary Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration The material that diffuses could be a solid, liquid or gas
Diffusion | Definition Examples | Britannica 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
Diffusion: Definition and How Does it Occur (with Diagram) - Science Facts Diffusion is defined as the movement of atoms, ions, and molecules from a region of high concentration to a region of low concentration, or ‘down their concentration gradient’ The word ‘diffusion’ is derived from the Latin word, ‘diffundere’, meaning ‘to spread out’ Diffusion
Diffusion Definition - BYJUS 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 – Definition, Causes, Significance, Examples Diffusion is a fundamental process involving the movement of particles, such as atoms, ions, or molecules, from an area of higher concentration to one of lower concentration This movement continues until the concentration is uniform throughout the medium, reaching equilibrium
DIFFUSION Definition Meaning - Merriam-Webster The meaning of DIFFUSION is the state of being spread out or transmitted especially by contact : the action of diffusing How to use diffusion in a sentence
Ficks laws of diffusion - Wikipedia Molecular diffusion from a microscopic and macroscopic point of view Initially, there are solute molecules on the left side of a barrier (purple line) and none on the right The barrier is removed, and the solute diffuses to fill the whole container Top: A single molecule moves around randomly Middle: With more molecules, there is a clear trend where the solute fills the container more and
8. 5: Effusion and Diffusion of Gases - Chemistry LibreTexts In a gaseous diffusion enrichment plant, uranium hexafluoride (UF 6, the only uranium compound that is volatile enough to work) is slowly pumped through large cylindrical vessels called diffusers, which contain porous barriers with microscopic openings The process is one of diffusion because the other side of the barrier is not evacuated
7. 7: Diffusion - Chemistry LibreTexts Diffusion refers to the phenomenon by which concentration and temperature gradients spontaneously disappear with time, and the properties of the system become spatially uniform As such, diffusion refers to the transport of mass and energy in a nonequilibrium system that leads toward equilibrium
