Question

Why do solids have a shape and volume?

Answer 1

1. In solids, particles are tightly packed, and hence the inter-molecular space is very small.
2. The inter-molecular forces of attraction in solids are very strong.
3. High inter-molecular force and negligible inter-molecular space do not allow the molecules to leave their mean position.
4. They can only vibrate in a fixed position.
5. Because of this position, solids are rigid and have definite shapes and volume.
