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 movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient ” Read on to explore what is diffusion and the different types of diffusion
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
10. 9: Diffusion - Chemistry LibreTexts Simple diffusion and osmosis do not involve transport proteins Facilitated diffusion requires the assistance of proteins Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration For cell transport, diffusion is the movement of small molecules across the cell membrane
What Are the Key Diffusion Characteristics? - Biology Insights As diffusion progresses and the concentration difference diminishes, the rate of diffusion naturally slows down Particle size and mass also impact diffusion Smaller and lighter particles generally diffuse more quickly than larger, heavier ones This is because smaller particles face less resistance and can move through a medium with greater ease
What Is Diffusion? - ThoughtCo Diffusion is the tendency of molecules to spread out in order to occupy an available space Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment Passive transport is the diffusion of substances across a membrane
Diffusion Explained - Definitions, Types, and Examples in Biology . . . Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, which is caused by their random motion We can define diffusion as a movement that occurs due to the random kinetic energy of molecules, which causes them to spread out
