Answer:
D. Melting point
Step-by-step explanation:
A physical property in which the temperature at which a substance in a solid state transforms to a liquid state is the melting point.
The melting point is an indicator of a phase change where solid changes to liquid.
- Boiling point is the temperature by which the vapor pressure of liquids excesses the atmospheric pressure
- Freezing point is the temperature at which a liquid change to solid
- Evaporating point is the point in which liquid changes to gas or vapor.
