Which of the following is NOT a property of an ideal gas?

• A. The gas particles experience no intermolecular forces.
• B. The gas particles are in constant, random motion.
• C. The gas particles lose energy during collisions.
• D. The gas particles have negligible volume compared to the container.

Answer: (C)

Verified step by step guidance

1. Recall the key assumptions of the ideal gas model: (1) Gas particles have negligible volume compared to the container, (2) Gas particles are in constant, random motion, (3) Gas particles experience no intermolecular forces, and (4) Collisions between gas particles are perfectly elastic, meaning no energy is lost during collisions.
2. Analyze each statement in the problem in light of these assumptions: The first statement says gas particles experience no intermolecular forces, which aligns with the ideal gas assumption.
3. The second statement says gas particles are in constant, random motion, which is also a fundamental property of ideal gases.
4. The third statement says gas particles lose energy during collisions. This contradicts the ideal gas assumption that collisions are perfectly elastic, so this is NOT a property of an ideal gas.
5. The fourth statement says gas particles have negligible volume compared to the container, which is consistent with the ideal gas model.
