SUMMARY
The diffusion coefficient (D) is quantified in units of cm²/s, representing the rate at which particles diffuse through a medium. This measurement can be understood through Fick's law, where flux is defined as the product of speed and density. Specifically, the diffusion coefficient indicates how speed varies with the density gradient, expressed as L²/T. Doubling the diffusion coefficient results in either a doubling of the speed or maintaining the same speed with a reduced density gradient.
