Why doesn the temperature of water continue to rise after it reaches boiling point?
Any additional heat does two things after water temperature reaches the boiling point. Some of the heat makes the water boil more violently, releasing dissolved gasses in it that bubble up and escape as the water boils, and some heat is used to evaporate the water, turning it into steam. Under certain conditions water can be ‘super heated’ above the boiling point, but this is not something that should be tried except in a proper environment with a knowledgeble person supervising.
