1.2 General Characteristics of solid and Classification of solid

·         The constituent particles are very closely packed i.e., inter-molecular distance are minimum.

·         Inter-molecular force between molecules to be maximum.

·         Solid substance occupy fix space.

·         They have definite shape and volume

·         They possess rigidity

·         They have high density

Classification of solid

Solid are of two types

1.       Crystalline solid

2.       Amorphous solid

Crystalline solid: - A solid substance in which atom molecule or ion regular arrange on their three dimensional figure is called crystalline solid.

Ex:- sodium chloride , graphite and diamond, etc.

Amorphous solid  :- a solid  substance in which atom molecule or ion irregular arrange on three-dimensional figure that is called amorphous solid.

Ex:- glass, rubber, plastic , all polymer ,etc.
