boiling point

For any given liquid, the temperature at which the application of heat raises the temperature of the liquid no further, but converts it into vapour.

The boiling point of water under normal pressure is 100°C/212°F. The lower the pressure, the lower the boiling point and vice versa.

In a pure solvent, elevation of boiling point can be achieved by the addition of a soluble substance. For example, the addition of salt to boiling water will stop it boiling and raise the boiling point.
