Class 12 NCERT Exemplar for Chemistry Chapter 1 The Solid State

The NCERT PDF for Solid State Chemistry, Class 12 is an excellent resource for grasping the major ideas in this chapter. 1st Chapter The term – I CBSE Syllabus for 2021-22 is assigned to the Solid State of Class 12 Chemistry. In addition to NCERT example questions, students should solve previous year problems and take mock tests to polish their skills.

Matter exists in three states. Solid, liquid, and gas are the three types. Solids have a variety of qualities, they are:

• Solids have a defined volume, mass, and shape.
• Force and distance: The distance between molecules is short, yet the intermolecular force is significant.
• Solids can’t be compressed because they’re hard.
• The positions of particles are fixed.

Amorphous and crystalline solids are the two forms of solids that exist. Long-range order is present in crystalline solids, which have a fixed geometric structure. These solids are isotropic and have no definite fusion temperatures. Quartz and sodium chloride are examples of crystalline solids. True solids are also known as crystalline solids.

The word amorphous comes from the Greek word amorphous, which means “without shape.” The particles in this have an indeterminate form and a short-range order. Quartz glass is an example of amorphous solids. Supercooled or pseudo solids are other names for amorphous solids.
