Diffusion is the net movement of molecules or atoms from a region of high concentration to a region of low concentration as a result of random motion of the molecules or atoms. 

Common Examples of Diffusion. You can smell perfume because it diffuses into the air and makes its way into your nose. A teabag placed in a cup of hot water will diffuse into the water. Placing food coloring in a liquid will diffuse the color.

Answer 2

The movement of materials from an high pressure area to a low pressure area is known as diffusion. Diffusion can occur in gases and liquids. In liquids, if it happens through a semi-permeable membrane, it is called osmosis.

Example, If there is CO2 filled in a room, and if you open that room, the air from outside and CO2 will diffuse with each other.
