Explain the properties of amorphous solids.

Text Solution

Verified by Experts

(1) Amorphous substances appear like solids but they do not have perfectly
(2) An amorphous solid does not have regular arrangement of constituent particles.
(3) The arrangement of constituent particles like atoms or molecules has only short range order hence periodically repeating regular pattern is only over a short distance.
( 4) Amorphous solids are called supercooled liquids of very high viscosity or pseudo solids.
(5) Physical properties do not change with change in directions hence amorphous solids are isotropic in nature.
(6) Amorphous solids do not have sharp melting points.
