Diffusion :
Diffusion is the net movement of molecules from an area of higher concentration to an area of lower concentration.
The difference in the concentration of a substance between two areas is called the concentration gradient.
Diffusion occurs in liquids and gases when their particles collide randomly and spread out.
Final answer:
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.
