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 …

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 …

Nov 21, 2023 · 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’.

Oct 4, 2019 · 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 …

Oct 8, 2025 · Diffusion is a passive process where molecules move from an area of higher concentration to lower concentration until equilibrium is reached. It is vital for biological functions such as …

Nov 19, 2025 · Diffusion is a fundamental process describing the net movement of atoms or molecules from an area of higher concentration to an area of lower concentration. This passive movement …

Diffusion is the natural movement of molecules spreading out from higher to lower concentration. Molecules diffuse through collisions due to random molecular motion. Diffusion is always happening, …

May 5, 2025 · Diffusion is the movement of a molecule down a concentration gradient, from an area of its high concentration to an area of its low concentration. This process is passive, i.e. it requires no …

“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 …

Learning Objectives By the end of this section, you should be able to: Define diffusion and explain how molecular kinetic energy drives the movement of substances down concentration gradients Compare …
