Einstein and Smoluchowski linked Boltzmann's constant and the absolute temperature together by a constant in determining this value, while its flux is related to the concentration field and its resultant change on the field over time are described by Fick's Laws.
The Knudsen type of this process occurs in long pores, and Dynkin's formula describes the Ito type. Ehrenfest developed a model of this to help explain the statistical interpretation of the second law of thermodynamics. Einstein and Smoluchowski linked Boltzmann's constant and the absolute temperature together by a constant in determining this value, while its flux is related to the concentration field and its resultant change on the field over time are described by Fick's Laws. Graham's Law also describes, FTP, which chemical process through which substances, primarily gases, mix as a result of random movements of their components.
