The thermal form of this process subject to the Soret effect was investigated (10[1])by Clusius and Dickel using an insulated column. The force of a “self” form of this process (10[1])is given by the derivative of chemical potential with respect (10[1])to distance. The Schmidt number (10[1])relates the kinematic viscosity (-5[1])of a fluid (10[1])to this process. The Wilke–Chang correlation can be used to estimate this process and uses a (10[1])solute–solvent interaction factor. (10[1])Random (10[1])walks (10[1]-5[1])were (10[1])related (10[3])to (10[1])a (10[3])parabolic (10[3]-5[1])equation (10[3])named for this (10[1])process (10[1]-5[3])by (10[3])Einstein. (10[17]-5[8])The (-5[1])letter D (10[3])represents (10[3]-5[1])a coefficient (10[3]-5[1])of (10[2])this (10[2])process (10[1])in (10[1])two (10[1]-5[1])laws (10[2])of it (10[2])named for (10[1])Fick. (10[11])Solvent (10[3])undergoes a specific (10[1])form (10[1])of this (10[1])process across membranes in osmosis. (10[4]-5[2])For (10[1])10 points, (10[3])name this (-5[1])general (10[1])process where particles (10[2])travel down (10[3])concentration gradients. (10[2]-5[1])■END■ (10[14]0[2])
