Detailed explanation-1: -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.

Detailed explanation-2: -Examples of Solid to Liquid (Melting) Ice to water-Ice melts back into water when it is left out at temperatures above the freezing point of 32 degrees. Rocks to lava-Rocks in volcanoes can be heated until they are molten lava.

Detailed explanation-3: -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).

Detailed explanation-4: -Melting occurs when a solid is heated and turns to liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place. Typically, during melting, the particles start to move about, staying close to their neighbouring particles, then move more freely.

Detailed explanation-5: -Melting is a process that causes a substance to change from a solid to a liquid. Melting occurs when the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid.
