Question

Statement: The amorphous solids are isotropic.

• A. True
• B. False

Answer 1

The correct option is A True

Amorphous solids

1. The amorphous solids are isotropic because they have identical physical properties in all directions due to irregular arrangement.
2. Amorphous solids do not have a long-range order however they may possess small regions of orderly arrangement.
3. An amorphous solid does not have a sharp melting point but melts over a range of temperatures, for example, glass on heating softens and then melts over a temperature range.
4. Amorphous solids when heated and then cooled slowly by annealing become crystalline at some temperature.

Therefore, an amorphous solid is isotropic due to its identical physical properties. Hence the above statement is true.
