What is the term used to describe the spontaneous intermingling of particles of different substances to form a homogeneous mixture?

💡 Solution & Explanation

Diffusion is the physical process by which matter spreads spontaneously from regions of higher concentration to regions of lower concentration until a uniform mixture is established. Osmosis specifically refers to the movement of solvent molecules across a semipermeable membrane, differing from general molecular diffusion. Diffusion plays a fundamental role in various biological transport mechanisms and chemical reactions.
