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 is defined as "The mixing of a substance with another substance due to the motion or movement of its particles".
The substance can be Solid, Liquid or Gas. It takes place from higher concentration to lower concentration, so as to spread uniformly without any external force applied . Since, diffusion depends on movement of particles. We can state that higher the Kinetic energy, higher will be the rate of diffusion in that substance. So, diffusion is highest in Gas, then liquids and negligible in Solids.
Everyday examples of Diffusion are :
(1) The smell of perfumes/Incense Sticks spreading evenly in the room when lightened.
(2) Sugar gets dissolved evenly and sweetens the water without having to stir it.
