Question

Amorphous solids are :

• A. Isotropic and supercooled liquids
• B. Anisotropic and supercooled liquids
• C. Isotropic and superheated liquids
• D. Anisotropic and superheated liquids

Answer 1

The correct option is A Isotropic and supercooled liquids

Amorphous solids have an irregular arrangement of constituent particles. They have the same physical properties in all directions due to irregular arrangement. Here the constituent particles (atoms, molecules or ions) are scattered and disordered. Hence the amorphous solids are isotropic.
Due to irregular arrangement they don't have sharp melting point. They have a range of temperature for melting.
They can be cut along random directions and have irregular surfaces.
The structure of amorphous solids is similar to that of liquids.
They are formed by sudden​ cooling of a liquid. Hence these are also called pseudo solids or supercooled liquids.
