"WebSo when water boils at 100 C at 1 atm, this means that only at 100 C does the vapour pressure of the water overcome the external vapour pressure. If you increase the external pressure to 2 atm, the water requires more energy to be able to overcome this pressure, therefore boiling point increases. this is how it works. " - H2o boil point
