Answer 1

The correct option is A True

1. A substance in the solid state when heated constantly until its melting point increases its temperature.
2. At the melting point, on absorbing the latent heat of fusion it converts from the solid state to the liquid state at a constant temperature.
3. Ice converts to water at 0 °C.
4. Until the change of state is completed, the temperature will not rise or fall.
5. Similar results are observed in other phase changes (boiling, freezing, etc.) also.

Hence, the given statement is true.
