Freezing Point Depression -- from Eric Weisstein's World of Chemistry
A colligative property that the freezing point T_f of a solution is lowered \Delta T_f by the concentration m of solute (measured in molals) according to \Delta T_f= K_f m, where K_f is the molal freezing point depression. For water, K_f [{\rm H}_2{\rm O}] = 1.86^\circ{\rm\ C\ molal}^{-1}. See also: Colligative Property, Boiling Point Elevation, Molal, Water
