MCQ
A pseudo solid is:
- AGlass
- BPitch
- C$\text{KCl}$
- ✓Glass and pitch both
✓
Answer
Correct option: 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.
