kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.
