Is melting point the freezing point
The freezing point of a solvent is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent. This phenomenon is used in technical applications to avoid freezing, for instance by adding salt or ethylene glycol to water. WitrynaThe freezing point is the temperature at which the liquid solvent and solid solvent are at equilibrium, so that their vapor pressuresare equal. When a non-volatile solute is …
