Question

Why are particles closely packed in solids and not in liquids or gases?

• A. Solids are hard and have a fixed shape
• B. stronger forces of attraction between particles in solids
• C. Solids have less intermolecular space.
• D. Particles in solids have low kinetic energy

Answer 1

Answer: (B), (C)

The correct options are
B

stronger forces of attraction between particles in solids

C

Solids have less intermolecular space.

Particles of matter are packed very closely packed. A very strong force of attraction exists between the particles and intermolecular space is almost negligible. Wheras in liquids and gases the forces of attraction are not strong and intermolecular spaces are high.
