Question

why the temperature of melting ice does not rise even though heat is being supplied continuously​

Answer 1

Because the Heat given is then utilized in overcoming the forces of attraction between the particles.

It is known as Latent Heat of Fusion.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

Once water starts boiling, all the heat supplied to it is used in conversion of water into steam at the boiling point of water.

Hence, there is no rise in its temperature.

$\large\boxed{\fcolorbox{blue}{yellow} {Additional Information }}$

★ Boiling point of liquid :

The constant temperature at which a liquid transforms into gaseous state is called the boiling point of the liquid.

★ Latent heat of fusion :

The amount of heat energy absorbed at constant temperature by unit mass of a solid to convert into liquid phase is called the specific latent heat of fusion.

★ Latent heat of vaporization :

The amount of heat energy absorbed at constant temperature by unit mass of a liquid to convert into gaseous phase is called the specific latent heat of vaporization.

Hope it helps!
