# NCERT Solutions for Class 12 Chemistry Chapter 1 The Solid State

## NCERT Solutions for Class 12 Chemistry Chapter 1 The Solid State

We know that there are three states of matter which are solid, liquid, and gas but in the first chapter of NCERT Solutions for Class 12 Chemistry we deal with only Solid State. It is an important chapter for both CBSE Board exam because it carries 5 marks in the chemistry examination. There are 26 questions in exercise and 24 intext questions in this chapter. The NCERT Solutions for Class 12 Chemistry Chapter 1 The Solid State are prepared by our subject experts. These NCERT solutions help students to grasp the topic thoroughly.

After completing NCERT Class 12 Chemistry Chapter 1 The Solid State students will be able to describe characteristics of solid state, differentiate between amorphous solids and crystalline solids, define crystal lattice and unit cell and also able to explain close packing of particles, describe different types of voids and close-packed structure etc. The NCERT  Class 12 Chemistry Chapter 1 talk about only solid state. Some of the properties of solids are -

• Solids have a definite shape and volume,
• Inetmolecularforce is strong
• Intermolecular distance is short.
• Solids are rigid so it cannot be compressed etc

In Chemistry Chapter 1 The Solid State of Class 12, solids are classified into two types: Crystalline and Amorphous.

 Property Crystalline solids Amorphous solids Shape Definite geometric shape Indefinite or irregular shape Melting Point Sharp M.P Diffused M.P Anisotropy Nature Anisotropic Isotropic
