Question
What happens to a liquid, when the vapour pressure
equals the atmospheric pressure?Solution
Ordinary evaporation is a surface phenomenon -since the vapor pressure is low and since the pressure inside the liquid is equal to atmospheric pressure plus the liquid pressure, bubbles of water vapor cannot form. But at the boiling point, the saturated vapor pressure is equal to atmospheric pressure, bubbles form, and the vaporization becomes a volume phenomena.
