Melting is the process by which a solid substance transforms into a liquid when it is heated to its melting point. This transformation occurs because the added heat energy increases the vibrations of the molecules in the solid, causing them to break free from their fixed positions in the solid structure. Melting can be observed in various substances, such as ice melting into water or metal melting to become molten metal. The temperature at which melting occurs is specific to each material and is known as the melting point.
