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 (-5[1])term that is paired with a local reaction term. A term representing this phenomenon is added to an advective flux term in an equation (10[1])named for drift and this phenomenon. This phenomenon’s coefficient is proportional to temperature and mobility, as identified by Einstein. The flux of this phenomenon is proportional (10[1])to a concentration gradient by Fick’s laws. (10[1])For 10 points, name this phenomenon in which particles move from high to low (10[1])concentrations. ■END■ (10[1])
