WebFurthermore, amorphous solids are characterized by a short range order. Examples of amorphous solids include polymers, rubbers, plastics and glass. If an amorphous solid is left for a long time below its melting point, it can transform into a crystalline solid. It can depict the same properties possessed by the crystalline solids.
