Question

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

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

Answer 1

Answer: (B), (C)

The correct options are
B

strong forces of attraction between particles

C

less intermolecular space

Particles in solids are packed very closely because there is a very strong forces of attraction 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.
