Which has the greater entropy at the same temperature: one mole of water vapor or one mole of liquid water?
Answer and explanation
Correct answer: C. Water vapor
- Step 1: Gas particles have much more freedom of movement. Step 2. More possible arrangements means higher entropy. Answer: water vapor. Why not the others: Gas molecules have vastly greater positional and rotational freedom of motion than condensed liquids, resulting in significantly higher standard molar entropy.
