Diffusion in liquids
Diffusion in liquids is the natural process where molecules move from areas of higher concentration to areas of lower concentration, driven by their random motion. This movement continues until the molecules are evenly distributed. It occurs because molecules are constantly vibrating and bumping into each other, which causes them to spread out over time. Diffusion is essential in many biological and chemical processes, such as how nutrients reach cells or how smells disperse in the air. It is a passive process, meaning it doesn't require energy, simply resulting from the inherent motion of particles.
