Dear Student,
Amorphous solid is a solid that lacks an ordered internal structure. These are solids with short-range order and irregular shapes of constituent particles. There nature is isotropic and they melt over a range of temperatures. They do not have a definite enthalpy of fusion.
Examples of amorphous solids are glass, rubber, plastic, etc.
Glass is a very important amorphous solid which is made by cooling a mixture of materials in such a way that it does not crystallize.
Properties of amorphous solids :-
- The intermolecular forces in amorphous solids are weaker than those in crystalline solids.
- They do not have a regular external structure and they do not have sharp melting points.
- The physical properties of amorphous solids are the same in all directions.
Happy Learning!
