Di water freezing point

Webfreezing point, temperature at which a liquid becomes a solid. As with the melting point, increased pressure usually raises the freezing point. The freezing point is lower than the melting point in the case of mixtures and for certain organic compounds such as fats. WebBoiling Point Elevation. Water boils at 100 o C at 1 atm of pressure, but a solution of salt water does not . When table salt is added to water the resulting solution has a higher boiling point than the water did by itself. The ions form an attraction with the solvent particles that then prevent the water molecules from going into the gas phase ...
