Here's why:

* Melting is the process of a substance transitioning from a solid state to a liquid state.

* Freezing is the process of a substance transitioning from a liquid state to a solid state.

These are essentially opposite processes occurring at the same temperature. At this specific temperature, the solid and liquid phases of the substance exist in equilibrium.

For example:

* Water melts at 0°C (32°F) and freezes at 0°C (32°F).

Note: The term "freezing point" is typically used to describe the transition from liquid to solid, while "melting point" describes the transition from solid to liquid. However, they are referring to the same temperature point.
