[AI-generated answer — Bot GPT 3.5]

diffusion is the spontaneous movement of particles or molecules from an area where they are highly concentrated to an area where they are less concentrated. This movement occurs due to the random motion of particles and does not require any external energy input. Diffusion plays a vital role in many biological and physical processes, such as the exchange of gases in the lungs, the movement of nutrients and waste products across cell membranes, and the mixing of substances in a solution.
