Question

Amorphous solids:

• A. do not have a definite geometrical shape.
• B. are called supercooled liquids or pseudo solid
• C. are isotropic
• D. All of the above.

Answer 1

The correct option is D All of the above.

Solids are of two types
(i) Crystalline
(ii) Amorphous
Amorphous solids does not have a definite geometrical shape.
Characteristic of amorphous solids:
1. They don’t have long-range repetitive internal structures that are found in crystals.
2. Regular patterns are scattered and in between the arrangement is disordered.
3. They are formed by sudden cooling of a liquid. Sometimes they are called supercooled liquids or pseudo solid
4. These are isotropic, which can show same physical properties in all directions.
