Question

A pseudo solid is:

• A. glass
• B. pitch
• C. KCl
• D. glass and pitch both

Answer 1

The correct option is D glass and pitch both

Pseudo solids (such as glass & pitch) lack a regular three-dimensional arrangement of atoms.

Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum.

Solids are most stable in crystalline form. However, if a solid is formed rapidly (for example, when a liquid is cooled suddenly), its atoms or molecules do not have time to align themselves and may become locked in positions other than those of a regular crystal. Such resulting solids are called Pseudo solids.

Hence, the correct option is $\text{D}$
