WebAll common solids will typically go through one of three types of transformations when heated: Changing from a solid to a liquid state such as when a metal, wax or ice is heated to its melting point, or the specific temperature at which melting occurs. Changing directly from a solid to a gas in a process known as sublimation.

Remember that temperature is a macroscopic quantity, telling the heat content of system. So if the crystalline solid is at its fusion temperature, and every atom in the crystals have equal interaction energy with each other (ignoring all defects of lattice), the whole solid should fuse simultaneously, thus having sharp melting point. png news latest update
