MELTING By Dhruv.Chauhan and Arusha.Nirvaan

MELTING, IS A PHYSICAL PROCESS THAT RESULTS IN THE PHASE TRANSITION OF A SUBSTANCE FROM A SOLID TO A LIQUID. THE ENERGY OF A SUBSTANCE IS INCREASED, TYPICALLY BY THE APPLICATION OF HEAT OR PRESSURE, RESULTING IN A RISE OF ITS TEMPERATURE TO THE MELTING POINT AT WHICH THE RIGID ORDERING OF MOLECULAR ENTITIES IN THE SOLID BREAKS DOWN TO A LESSER STATE AND THE SOLID LIQUEFIES. Example Ice to water Gold to liquid gold Ice – cream to flavored milk

FACTS ON MELTING Melting means to be changed from a solid to a liquid state especially by the application of heat. To dissolve: Sugar melts in water. Ice requires approximately 80 calories of heat to change each gram to water at its melting point
