Once water has been heated to its boiling point, additional heating will not raise its temperature. what happens to this additional energy? a. energy was used to change phase of water from liquid to gas (evaporation). it is radiated back into the atmosphere from the stove. b. the extra energy is absorbed by the water and is stored for use at a later time. c. extra energy is turned into potential energy and is stored in the liquid water molecules. d. energy was used to change phase of water from liquid to gas (evaporation). it is stored in the water vapor produced.
