Detailed explanation-1: -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.
Detailed explanation-2: -Melting occurs when a solid is heated and turns to a liquid and freezing occurs when a liquid is cooled and turns to a solid. Melting-solid to liquid. When a solid is heated, its particles gain enough energy to overcome the bonding forces holding them firmly in place.
Detailed explanation-3: -The change in the solid to liquid phase at a constant temperature is called melting (or fusion). The temperature at which melting occurs is called the melting point of the solid.
