diffusion processes

Diffusion is the natural process where particles spread from an area of higher concentration to an area of lower concentration, driven by random movement. For example, when perfume is sprayed, its molecules move through the air, dispersing evenly over time. This process occurs in gases, liquids, and even solids, and helps explain phenomena like the mixing of flavors in food or the way oxygen enters our blood. Diffusion occurs spontaneously and gradually, constantly balancing out differences in concentration without requiring external effort.
