One quantity characterizing this process is proportional to temperature to the 3/2 power divided by a "collision integral" according to Chapman-Enskog theory.
One quantity characterizing this process is proportional to temperature to the 3/2 power divided by a "collision integral" according to Chapman-Enskog theory. In a plasma, the presence of an electric field between ions and electrons causes them to experience this process at equal rates in an ambipolar form of this process. The previous quantity characterizing this process is proportional to the product of the mean free path and the mean velocity and it is equal to the square of the (*) step size divided by the time between steps when using a random walk to model this process. The flux of this process is equal to minus the product of a namesake coefficient and the concentration gradient by Fick's 1st law. For 10 points, name this process exemplified by osmosis where molecules move from regions of high to low concentration.
