Question

Solids do not flow because the molecules

• A. Are held tightly together by strong forces of attraction.
• B. Are loosely packed.
• C. Are very loosely packed.
• D. None of these.

Answer 1

The correct option is A

Are held tightly together by strong forces of attraction.

1. The matters which are able to flow are called fluids.
2. Liquids and gases can flow. So they are called fluids.
3. In solids, the particles are closely packed and the intermolecular force of attraction is very high.
4. Thus, particles of the solids are held at a fixed point.
5. They don't have the freedom to move, they can only vibrate about their position.
6. Thus, solids can not flow.

Hence, option A is the correct answer.
