Question

why are solids rigid?​

Answer 1

Answer:

The atoms and molecules of solids are held together by pulling forces called bonds. The atoms in solids are held together by interatomic forces. ... It is this lack of mobility which makes a solid rigid.

Answer 2

Answer:

Solids are rigid because of the intermolecular forces of attraction present in the solid.

The intermolecular forces existing among the constituent particles of solid are very strong. That’s why the particles of solid cannot move from their positions, they only vibrate about their mean positions.
