Describe the two types of vaporization

There are two types of vaporization:  evaporation and boiling Evaporation is a phase transition from the liquid phase to a vapor (a state of substance below critical temperature)  that occurs at temperatures below the boiling temperature at a given pressure.  Evaporation occurs on the surface.

Work done = force ×distancebut force = mass ×gravityand gravity = 10m\s force = 2×10 = 20 work done = 20×3 = 60 joules
