What is the relationship between boiling point and pressure?
Well there is a relationship between boiling point and AMBIENT pressure.
The boiling point of a liquid are the conditions of temperature and (ambient) pressure when the VAPOUR PRESSURE of the LIQUID is equal to the ambient pressure, and bubbles of vapour form directly in the liquid. The
It follows when we reduce the ambient pressure, the boiling point of the liquid should reduce. And this is the principle of vacuum distillation: if the pressure is reduced, an otherwise involatile liquid may be distilled at a reduced temperature (compared to its
