DIFFUSION Meaning and
Definition
-
Diffusion is a process in which particles or molecules move from an area of high concentration to an area of lower concentration, resulting in the spread or dispersion of substances. It occurs due to the random motion and collision of particles, allowing them to distribute evenly throughout a given space. Diffusion plays a significant role in various natural and man-made processes.
In the context of gases, diffusion commonly refers to the mixing of gases, such as when a scent spreads through a room or when air pollution disperses in the atmosphere. However, diffusion is not limited to gases; it also occurs in liquids and solids. In liquids, diffusion is responsible for the spread of substances, like when sugar dissolves in water. Similarly, in solids, diffusion allows atoms or molecules to move and redistribute, leading to the equalization of concentrations.
The rate of diffusion depends on several factors, including temperature, pressure, concentration gradient, and the nature of the particles involved. Higher temperatures and lower pressures generally increase the rate of diffusion, while larger concentration differences between two regions enhance the speed at which substances diffuse.
Diffusion is fundamental in many biological processes, including the exchange of gases in the lungs and the movement of nutrients and waste products across cell membranes. It is also crucial in chemical reactions, such as in the transport of ions in electrolytes or in the spread of odor molecules in the air. Additionally, diffusion has practical applications in fields like engineering, medicine, and environmental studies.

Etymology of DIFFUSION
The word "diffusion" originates from the Latin word "diffusio", which comes from the verb "diffundere". "Diffundere" consists of two parts: "dis-" meaning "apart" or "away", and "fundere" meaning "to pour". Therefore, "diffusion" essentially means "the action of pouring or spreading apart". In the context of diffusion, it refers to the process of particles or substances spreading and mixing in various directions.
