The vapour pressure is the pressure exerted when the molecules leave the surface at the same rate as they return. The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases. Evaporation is a phase transition from the liquid phase to vapour (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure.

Increasing pressure usually increases the boiling point of a liquid. If a substance is in a closed container at the boiling point, then the liquid is boiling and the gas is condensing at the same rate without net change in their relative amount.

When you have a liquid (in 1 atmosphere of air pressure) we define its boiling point when its vapor pressure is equal to atmospheric pressure. The amount of heat needed to change the temperature of a substance will vary with the types of substance. The vapor pressure of a substance is related to temperature, so increasing the temperature increases the vapor pressure till it =1 atmosphere and.
