Question

Explain why liquids can flow but are not compressible.

Answer 1

Liquids:

1. Liquids have definite volume but no definite shape.
2. There is an intermolecular force of attraction between the molecules of a liquid.
3. Liquids have the property to flow because they have the less intermolecular force of attraction as compared to solids.
4. In liquids, the particles have enough energy to partially overcome intermolecular attraction.
5. The particles can move while remaining in contact.
6. So, liquid particles are still in close contact having definite volume.

Liquids can flow but are not compressible because the particles are packed close together.
