Question

define diffusion and explain​

Answer 1

Answer:

Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. ... Diffusion may also be thought of as the movement of particles down a concentration gradient. The term "diffusion" comes from the Latin word diffundere, which means "to spread out."

Answer 2

A diffusion is a process in science . Some particles are dissolved in a glass of water. At first, the particles are all near one top corner of the glass. If the particles randomly move around ("diffuse") in the water, they eventually become distributed randomly and uniformly from an area of high concentration to an area of low concentration, and organized (diffusion continues, but with no net flux).
