Question

when a liquid boils its temperature remains the same so where does the heat go?

Answer 1

First of all, the temperature of the liquid does not be same. It rises. The boiling point of water is 100° C. The heat is present there only. When the temperature lowers down, the heat too gets cooled.

Answer 2

Whenever a liquid boils its temperature remains same and heat produced in boiling gets converted into kinetic energy and it remain in liquid.

For instance, you might have seen whenever we boil water liquid shows movement.
