"The boiling point"The boiling point is defined as the temperature.......

Explanation:

The "boiling point"boiling point is defined as the temperature at which the vapour pressure of the liquid is equal to the ambient pressure, and bubbles of vapour form directly in the liquid. The "normal boiling point"normal boiling point is specified when the ambient pressure is 1*atm1atm.

Of course, if we reduce the ambient pressure, the boiling point will be substantially reduced, and this is an example of the principle of "vacuum distillation"vacuum distillation, where an otherwise involatile liquid is distilled under high vacuum.
