👉 The concept of diffusion is a fundamental property of matter that describes how particles move through a medium. In physics, it can be defined as the ability of a substance to transport or distribute its own molecules and ions at a constant velocity across a certain distance in a given direction. Diffusion is a key process in many physical phenomena, including the movement of gases and liquids, the diffusion of substances into and out of solutions, and the formation of biological macromolecules. Diffusivity is a measure of
