CBSE Class 12 Chemistry Notes : The Solid State

By Anuj William - 4 years ago

     

Solids

Solids are the chemical substances which are characterised by define shape and volume, rigidity, high density, low compressibility. The constituent particles (atoms, molecules or ions) are closely packed and held together by strong interparticle forces

Types of Solids

The solids are of two types : Crystalline solids and amorphous solids.

Distinction Between Crystalline and Amorphous Solids

S.No Crystalline solid Amorphous solids 1 These have definite and regular arrangement of the constituent particles in space. These doesn’t have any regular arrangement of the constituent particles in space. 2 These are true solids. Theseare super cooled liquids or pseudo soilds. 3 These have long order arrangement of the particles. These have short order arrangement of particle. 4 These are anisotropic in nature, i.e., their physical properties are different in different directions. These are isotropic in nature i.e., their physical properties are same in all the directions. 5 They have sharp melting points. They melt over a certain range of temperature. 6 They undergo a clean cleavage when cut. They undergo irregular cleavage when cut.

Answer 2

solid state :

solids are characteristics by the state of matter in which particles are closely packed and held together by strong intermolecular attractive forces.

properties of solids

• in solid state the particles are not able to move randomly.
• they have definite shape.
• solids have high density

types of solid

a solid can be classified as crystalline solids for amorphous solids.

⏩crystalline solids= crystalline solid usually consists of a large number of crystals each of them having a definite characteristic geometrical shape.

,⏩amorphous solids=amorphous solids have no precise is melting point but when heated becomes increasingly piable until they assume their properties usually associated with liquids .
