AI overview
Diffusion is the process where particles randomly move around and gradually spread out from areas where they're concentrated to areas where they're sparse, until they're distributed evenly throughout. This matters because it's a fundamental way that substances mix and spread in liquids and other materials, happening naturally without any external force pushing them along.
