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.

WebBoiling Point of water. ... As you move to higher elevations (lower pressure) the boiling temperature will decrease. For example, although water normally boils at 100 o C (212 o F), on Mount Everest (elevation about 27,000 feet) water boils at 68oC (154oF). That is a dramatic difference. Sometimes you also see an example of this in baking. WebThe melting/freezing and boiling points change with pressure. The boiling point of water varies with atmospheric pressure. At lower pressure or higher altitudes, the boiling point is lower. At sea level, pure water boils at 212 °F (100°C). At the lower atmospheric pressure on the top of Mount Everest, pure water boils at about 154 °F (68°C).
