Tossup

In a fully ionized plasma, this phenomenon is proportional to ion velocity times the square of the Larmor radius, which produces a one-half-power dependence on electron temperature. The KPP equation is a one-dimensional form of a system in which this phenomenon is represented by a diagonal matrix multiplying a Laplacian term (10[1])that is paired with a local reaction term. A term representing this phenomenon is added to an advective flux term in an equation named for drift and this phenomenon. This phenomenon’s coefficient is proportional to (10[1])temperature and mobility, as (10[1])identified by Einstein. The flux (10[2])of this phenomenon is proportional to a concentration gradient by Fick’s laws. (10[3])For 10 points, name this phenomenon in which particles move from high (10[1])to (10[1])low concentrations. ■END■
