Chemistry chp no: 1. Solid State
Chapter 1 – Solid State Class 11 Chemistry | Maharashtra State Board 1.1 Introduction In the solid state, the particles are held together by strong interparticle forces of attraction. Because of these strong forces, solids have a definite shape and a definite volume. When temperature or pressure changes, the shape and volume of a solid change only slightly. The smallest particles present in solids may be atoms, ions or molecules. In this chapter, all these smallest particles are called constituent particles or simply particles . Key Points Strong attraction exists between the particles of a solid. Solids have a fixed shape. Solids have a fixed volume. Changes in temperature and pressure produce only small changes in solids. The particles of solids may be atoms, ions or molecules. 1.2 Types of Solids Solids are divided into two main types. Type of Solid Description Crystalline Solid Particles are arranged in ...
