The energy is used to maintain the temperature at the boiling point.
The energy is used to maintain the temperature at the boiling point.
The melting point is the temperature at which a solid changes phases into a liquid. This is a result of the highly structured atoms of the solid, which have very little kinetic energy beginning to gain energy and dissociate. The boiling point is the temperature at which a liquid changes into a gas. This happens when the atoms/molecules of a liquid gain enough kinetic energy to escape the liquid and move into the gaseous state.
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
Water evaporates at any temperature. Some water molecules have enough energy to leave the surface of the liquid. As the temperature increases more and more molecules have enoughenergy to leave the surface of the liquid. At the boiling point all molecules have enough energy to evaporate. Bubbles of vapour form throughout the liquid (we see these bubbles as proof of boiling).
If you add energy to a boiling liquid, it will just boil faster, but the temperature will remain the same, at the boiling point. All the energy goes into phase change, not heating.

No, boiling water is at a plateau of hotness and enough energy must be added and the water will change state and become steam which can be heated mych hotter.
The boiling point of water is 100 degrees celsius. The water will evaporate at boiling point. By the way what do you mean "what happens to the temperature of boiling water" if you think about it, it does not make sense.

what happens to molecules as energy is added the temperature increses

it is hot temperature but when thermal energy leaves the temperature is cool
There's actually no need to measure the temperature boiling water. If water is boiling, it will always be 100°. This is because boiling is a cooling process. As you apply heat, water molecules who want to boil, breaking free and enter the gaseous phase. When this happens, they take some of the energy that you imported into the liquid with them. Thus once the liquid reaches the boiling temperature water will continue to evaporate until there is no more water left. During this time, it will remain 100°.
