1.7 Rates of Processes: Diffusion (Thermal Physics) (Schroeder)

When we consider the motion of particles from one region to another, we are considering diffusion. Diffusion is the process whereby particles move due to a difference in concentration. Here we cover Fick's Law, the Diffusion Coefficient.

The textbook I am using is: Schroeder, Daniel V. "An Introduction to Thermal Physics" 1st ed., Addison Wesley Longman, 2005.
