Answer:

The melting and freezing points of a substance are the same

Explanation:

Melting occurs when the state of a substance changes from solid to liquid, while freezing occurs when the state of a substance changes from liquid to solid. Therefore, melting and freezing are one the inverse process of the other: it means that they occur at the same temperature.

For instance, the melting point of ice (at standard pressure) is \(0^{\circ}\), and the freezing point of water is at the same temperature, \(0^{\circ}\).
