Answer:
See the answer below
Explanation:
The temperature stops rising when water begins to boil because the heat which causes the rise in temperature is now diverted into changing the phase of the boiling water.
The conversion of substances from one state of matter to another requires energy. Hence, instead of causing a rise in the temperature of the boiling water, the heat is used to convert the liquid water into vapor. The heat thus becomes what is known as the latent heat of vaporization.
