Heat energy get used up in changing State of water
Explanation:-
The temperature remains constant during boiling of water even though heat is supplied constantly because all the heat energy provided is used up in changing the state of water from liquid to gaseous water vapour. Therefore all the heat energy provided to the liquid increases the kinetic energy of the particles and temperature doesn't increase. So supplied heat energy is used to increase kinetic energy of molecules.

Answer:
This heat gets used up in changing the
state by overcoming the forces of attraction
between the particles. As this heat energy is
absorbed by ice without showing any rise in
temperature, it is considered that it gets
hidden into the contents of the beaker and is
known as the latent heat. The word latent
means hidden.
