Question

6 why do particles in a liquid have more freedom of movement than in a solid? a solids have no space for particle movement b external pressure in liquids is always lower c intermolecular forces are weaker in liquids than in solids d liquids have higher energy barriers than solids

Explanation:

• Option A: Solids do have some particle movement (vibrational), so this is incorrect.
• Option B: External pressure isn't the key factor for particle freedom in liquid vs solid.
• Option C: In liquids, intermolecular forces are weaker than in solids. Weaker forces mean particles can move more freely.
• Option D: Higher energy barriers would restrict movement, not allow more freedom.

Answer:

C. Intermolecular forces are weaker in liquids than in solids
