Question

a vessel containing water is kept on an oven. the temperature of water increases as heat is supplied to it from the oven. But the temperature stops rising when the water begins to boil. What is the reason for this? where does the heat go then?

Answer 1

See the answer below

Step-by-step 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.
