All of the water molecules gain a lot of energy and eventually leave the liquid into the "air" as a gas. So basically they move fast enough to turn into a gas.
When you add kinetic energy to a solid the molecules won't move
Of course, because kinetic energy of molecules is directly proportional to temperature.
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
The particles move faster. Thermal energy is a measure of kinetic energy of molecules.
The faster a molecule moves, that hotter it becomes. If water becomes hot enough, it evaporates into steam.
they spread apart and move faster when energy is added.
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.

They move faster because the heat gives them more energy
the atoms use the energy to move the molecules
As water is heated, the water molecules gain kinetic energy and they move faster. Eventually, they get enough kinetic energy to move fast enough to escape the liquid phase and become a gas/vapor. This is the boiling point.

The liquid cools down. Its molecules move more slowly.
