Difference between Melting and Smelting Melting vs

2017-10-20  Melting is a process of changing or converting the state of a substance from solid to liquid form. It is a simple process of heating the substance to its melting point where the substance starts to liquefy. Many times substances are put under great pressure to melt them and also a combination of heat and pressure is used.
