Which of the following statements is true? the melting and freezing points of a substance are the same. the melting and boiling points of a substance are the same. the freezing and boiling points of a substance are the same. the heat of fusion and the heat of vaporization for a substance are the same.

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 , and the freezing point of water is at the same temperature, .

i think the answer would be b
