Ncert Solutions Chemistry Class 12th

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

1.2 They are rigid so the intermolecular forces of attraction that are present in solids are very strong. Hence, solids have a definite volume.

1.1 : It is because of the lack of mobility which makes a solid rigid. Since the atoms are almost lacking in mobility, their kinetic energy is negligibly small. The constituent particles in solids are held together by strong inter-atomic forces. The average location of the particles in a lattice does not change with time.
