Melting vs. Freezing Point: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 27, 2023
Melting point is the temperature at which a solid becomes a liquid; freezing point is the temperature at which a liquid becomes a solid.

Key Differences

Melting point is defined as the temperature at which a solid substance transitions to its liquid state. In contrast, freezing point is the temperature at which a liquid substance turns into a solid. Both represent a phase change, but in opposite directions.

Substances with a high melting point require more heat to transform from solid to liquid, indicative of strong molecular bonds. Conversely, substances with a low freezing point can remain liquid at lower temperatures, useful in applications like antifreeze.
