The normal boiling point ... pump a liquid from lower pressure area to a High pressure area. To increase Flow rate. To move liquid from lower elevation to higher elevation. 4. 4. Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
