Class- 12th "SOLID STATE"
General Introduction of Solid State "Solid is the one of four fundamental states of matter. The particles(atom, molecules, or ions)in solid state are closely packed together and contain the least amount of kinetic energy." Characteristics of Solid state • Particles distance is minimum. • Size,volume, mass, and shape are absolute. • Density is greater than gas and liquid states • Moving character are less than liquids and gases. • Solids are heavier than liquids and gases. ( exception ice is lighter than water) • Particles are bound strongly by intramolecular forces. Classification of solid state On the basis of the nature of order present in the arrangement of their constituent particles. A- Crystalline Solids It is a solid whose particles posses a regular order a long range arrangement. Fig. 1: arrangement of crystalline ...
