Detailed explanation-1: -Melting or fusion is a physical process that results in phase transition of substance from solid to liquid. This occurs when internal energy of solid increases, typically by absorbing heat or pressure which increases substances temperature to melting point.

Detailed explanation-2: -Melting: The transition from the solid to the liquid phase. Freezing: The transition from the liquid phase to the solid phase.

Detailed explanation-3: -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-4: -Melting occurs when a solid is heated until its particles reach a high enough energy to reach its melting point, changing it into the liquid state. An example of melting is an ice cube turning into liquid water when you set it on a surface, or hold it in your hand.

Detailed explanation-5: -The conversion of a solid to a liquid is called fusion (or melting). The energy required to melt 1 mol of a substance is its enthalpy of fusion (Hfus). The energy change required to vaporize 1 mol of a substance is the enthalpy of vaporization (Hvap). The direct conversion of a solid to a gas is sublimation.
