Diffusion in liquid: If we drop a little ink in a beaker of water, it will spread by itself in the beaker of water and the color spreads uniformly due to diffusion.

Diffusion in solids: When chalk marks are left on the black board for a long time it penetrates into the board very strongly due to diffusion.
