Boiling point is the temperature at which vapour pressure of liquid becomes equal to the atmospheric pressure. More is the vapour pressure lesser will be the heat require to raise its vapour pressure . So more is the vapour pressure lower is the boiling point .
There are two factors that determine a liquids boiling point: temperature and pressure. For water to be boiled at 20oC (room temperature - more or less), it would hâ¦ave to be subjected to about 2.339 kilopascals. See link below for more conversions.
