Diffusion is net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.

Diffusion in solids is very, very slow process. Example: If we write something on a blackboard and leave it uncleaned for a considerable period of time, we will find that it becomes quite difficult to clean the blackboard afterwards.

You can smell perfume because it diffuses into the air and makes its way into your nose. Diffusion of gasses takes place where there's a high concentration of one gas which is released into a lower concentration gas.

A teabag placed in a cup of hot water will diffuse into the water. Placing food coloring in a liquid will diffuse the color.
