Comparing intermolecular forces and particle distances in solids vs. liquids Steps:

• Identify that solids have particles in fixed, vibrating positions due to strong attractive forces.
• Note that liquids have particles that slide past each other due to weaker forces and more space.
• Compare forces: solid forces are stronger to maintain structure against liquid's mobility.
• Compare distances: solid particles are closer together than in liquids, where gaps allow flow.

Why C is correct:

• Stronger forces and smaller distances in solids match the kinetic molecular theory, where fixed lattice requires tight packing and robust attractions.

Why the others are wrong:

• A: Distances in solids are smaller, not greater, than in liquids.
• B: Forces in solids are stronger, not weaker, than in liquids.
• D: Forces in solids are stronger, not weaker, than in liquids.

Final answer: C
