Answer:

Diffusion is the mixing of a substance with another substance due to the motion of its particles. The smell of perfume spreads over a whole room is an example for diffusion.

The carbon dioxide and oxygen gas present in air diffuse into water, and dissolve in it.

This is an example of diffusion of gases into a liquid
