when a liquid is heated it will break . The molecules there will be vibration of molecules and then they will loosen up(the molecules that is) and then there will be a lot of heat which will remain constant and then the heat will make the liquid to evaporate (which is known as boiling point)

we would need to see the picture to answer it
