Question

Solids are generally denser than liquids because

• A. the particles are loosely packed in solids than in liquids.
• B. the particles are closely packed in solids than in liquids.
• C. the particles of solids have lesser weight than the particles
  of liquids.
• D. none of these

Answer 1

The correct option is B

the particles are closely packed in solids than in liquids.

1. Solids are known to have definite shape and volume.
2. Liquids are marked by their property to have the ability to adapt to the shape of the container they are kept in while keeping a definite volume and gases are marked by their property to be able to adapt to both shape as well as the volume of the container they are stored in.
3. The particles in solids are present very close to each other and the intermolecular gaps are very less.
4. The intermolecular forces are thus high giving them making them rigid and dense.
5. Thus, solids are denser than liquids and gases.

Hence, option B is correct.
