Is the pressure at which liquid and vapour can coexist in equilibrium; the rate of evaporation is equal to the rate of condensation. Vapour pressure increases with temperature. Vapour pressure is independent of the amount of liquid present.A liquid boils when its vapour pressure is equal to the atmospheric pressure, or other external pressure.
