Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.
Melting is the process by which a substance changes from the solid phase to the liquid phase. Learn the scientific glossary definition of melting, along with a practical, easily understandable real-life example.
melting, change of a solid into a liquid when heat is applied. In a pure crystalline solid, this process occurs at a fixed temperature called the melting point; an impure solid generally melts over a range of temperatures below the melting point of the principal component.

Melting is defined as the process of converting a substance from the solid to the liquid state of matter. A chemical that exists in its liquid state can be changed back into a solid state in a process known as fusion , which is more commonly-known as "freezing.
Melting is the conversion of a solid to a liquid. When a solid is converted directly to a gas, the process is known as sublimation. The reverse processes are freezing and deposition, respectively. …
Jun 4, 2024 · melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
The melting point is the temperature at which the substance goes from a solid to a liquid (or from a liquid to a solid). The boiling point is the temperature at which a substance goes from a liquid to a gas (or from a gas to a liquid).
