Diffusion

The process by which molecules spread from areas of high concentration to areas of low concentration, often leading to equilibrium.

Osmosis

The process by which molecules of a solvent pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.

Filtration

The process of separating solids from liquids or gases using a filter medium that allows only the fluid to pass through.
