WebVaporization. Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. [1] There are two types of vaporization: evaporation and … WebBoiling occurs IF AND ONLY IF the vapour pressure of the water overcomes the external vapour pressure. So it's not the pressure of the water itself, it has to do with the vapour pressure. So 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. screening mvc
