What is the melting point of a solid?

1. Heating a solid raises its temperature until it changes state. 2. The temperature at which it turns into a liquid is its melting point. 3. The boiling point is a different temperature, where a liquid turns into a gas. 4. Each substance has its own melting point and its own boiling point. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Boiling and melting points_
