Boiling point elevation works along the same pricnipals as freezing point depression, except that it is on the opposite end of the spectrum. When a solute is added to a solvent, the boiling point of the new solution is raised. As with freezing point depression, the magnitude of the boiling point elevation depends upon the concentration of the solute. This can also be represented by an equation that is similar to that of freezing point depression:

DeltaT=Kb msolute

with Kb being the molal boiling point elevation constant and msolute being the molality of the solute in the solution.
