Solids (Continued)
Solids are characterised by the state of matter in which particles are closely packed 
and held together by strong intermolecular attractive force.
(1) Properties of solids :
(a) In solid state the particles are not able to move randomly.
(b) They have definite shape and volume.
(c) Solids have high density .
(d) Solids have high and sharp melting point which depends on the strength or 
value of binding energy.
(e) They are very low compressible.
(f) They show very slow diffusion.

(2) Types of Solids:
(1)Crystalline Solids (2) Amorphous Solids
(1) Crystalline Solids
(a) In this type of solids the atoms, molecule or ions are arranged in a regular pattern 
in the three dimensional network.
(b) They have sharp melting point and definite heat of fusion.
(c) They are anisotropic in nature. Anisotropic means they exhibit different physical 
properties in different directions. eg. The electrical and thermal conductivities are 
different in different directions.
(d) They are generally incompressible.
(e) The general examples of crystalline solids are Quartz, diamond etc.

(2) Amorphous Solids:
(a) In this type of solids, the arrangement of building constituents is not regular. 
However, they may possess regular pattern upto very small distances and hence, they 
are also known as short range solids.
(b) hey are regarded as super cooled liquids with high viscosity in which the force of 
attraction holding the molecules together are so great, that the material becomes
rigid but there is no regularity in structure.
(c) hey do not have sharp melting points.
(d) They are isotropic as they exhibit same physical properties in all the directions.
(e) he general examples of this solids are glass, Rubber, plastics etc.
