Answer 1

The correct option is A

melting point

The melting point of a substance is the temperature at which it changes state from solid to liquid. Ice melts at 0 ${}^0\text{C}$ and iron melts at 1540 ${}^0\text{C}$. Solids have a definite melting point. For a pure substance melting point and the freezing point are same.
