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
