Boiling Point Elevation-  Elevation in boiling point refers to increase in boiling boint of solvent upon the addition of solute. When a non-volatile solute is added then resulting solution has a higher boiling point then pure solvent. For example- Boiling point of Salt+water solution is more than pure water.
 
 
Freezing Point Depression-Freezing Point Depression refers to lowering of the freezing point of solvents upon the adition of solute. When  a non-volatile solute is added then resulting solution has a lower freezing point then pure solvent.
