diffusion coefficients

Diffusion coefficients measure how easily particles spread out in a medium, like gas, liquid, or solid. Imagine dropping food coloring in water; the rate at which the color spreads is influenced by the diffusion coefficient. A higher coefficient means particles mix quickly, while a lower one indicates slower mixing. This concept is important in various fields, such as chemistry, biology, and environmental science, helping us understand processes like nutrient absorption in cells or pollution dispersion in air and water. Essentially, it quantifies the ease of movement for particles in different environments.
