Melting point Definition & Facts Britannica
WebIn general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. Adding a heat will convert the solid into a liquid with no temperature ... WebMar 28, 2024 · The melting point of a solid is the same temperature as the freezing point of its liquid. They are simply approached from opposite directions. When a substance is at its melting point or freezing point, the solid and liquid states of that substance are present in equilibrium. For water, this equilibrium occurs at 0°C.
