1.3 Amorphous solids: Amorphous solids are solids in which the geometry of the solid is said to be irregular. When the amorphous solids are cut with a knife, a clean surface is not obtained. The amorphous solids are called pseudo solids or sometimes also as super cooled liquids. Polyurethane, Cellophane, Polyvinyl Chloride, Fiberglass, Teflon.
Crystalline solids: Crystalline solids are solids in which the geometry of the solid is said to be regular. When the Crystalline solids are cut with a knife, a clean surface is obtained. Crystalline solids are also called true solids.Naphthalene, Benzoic acid, Potassium nitrate, and Copper
