Classification of solids The solids are categorised into categories – A. Crystalline solids.         B. Amorphous solids. Distinction between crystalline and amorphous solids – i) Crystalline solids have a regular arrangement of particles whereas the amorphous solids have a completely random particles arrangement. ii) Crystalline solids have different physical properties ( eg. – Thermal conductivity, electrical conductivity … Read more
