Existence of matter as solid, liquid or gas depends upon the net effect of intermolecular forces and thermal energy. Solid state have definite mass. volume and shape. They are incompressible, rigid and intermolecular forces are strong. 2. Solids can be classified into two categories, viz. crystalline and amorphous depending upon the arrangement of constituent particles. 3. Crystalline solids (or true solids) have long range order of arrangeme of constituent particles and are anisotropic in nature, i.e. Cu, Ag etc. They melt at a sharp and have characteristic temperature. They have a definite and characteristic enthalpy of fusion. On the basis of nature of intermolecular forces operating in them the crystalline solids have been classified into following four types :     (i) Molecular solids Constituent particles are.       molecules which are bonded
