Did you mean Diffusion Constant?

GlossaryDiffusion Coefficient (Diffusion Constant)

measure of how quickly particles spread in a medium

The diffusion coefficient, also known as diffusivity, is a measure of how quickly molecules or particles spread out over time in a given medium, such as air, water, or within biological tissues. It quantifies the rate at which substances move from areas of high concentration to areas of low concentration, and is influenced by factors like temperature, medium viscosity, and the size of the diffusing particles.
