Fick's law is similar to Fourier's law, except that mass instead of energy is being transported.

Question

Quizplus · Accepted Answer

Fick's law describes the diffusion of mass through a medium, while Fourier's law deals with the conduction of heat (energy) through a material. Both laws describe the transport of a quantity (mass or energy) in response to a gradient (concentration gradient for Fick's law, temperature gradient for Fourier's law).
