Answer Posted / manojsiva v
The boiling point of an element or a substance is the temperature at which the vapour pressure of the liquid equals the environmental pressure surrounding the liquid.At higher surrounding atmospheric pressure,more amount of water(suppose) has to be converted into vapour state inorder to get eqalized with the surrounding environmental pressure.So to enable more amount of vapour formation means more amount of temperature required.Hence as atmospheric pressure increases,vapour pressure requirement increases and high temperature of liquid.thus higher boiling point.
