Chapter- 1 The Solid State
This chapter explains the general characteristics of the solid state, the classification of solids, the crystal lattice, unit cell imperfections, and solids. The matter has three states – solid, liquid, and gas. Solids are then divided into – amorphous and crystalline. Amorphous has no form, and Crystalline has a definite shape. NCERT Solutions is a perfect guide to get a firm grasp on these concepts. For further reinforcement of concepts, students can also access NCERT sample solutions available on Physics Wallah.
