Entropy, which is a measure of the disorder of a system, is__________________?
Correct answer: C. Zero at absolute zero temperature for a perfect crystalline substance
- A. Independent of pressure
- B. Independent of temperature
- C. Zero at absolute zero temperature for a perfect crystalline substance
- D. All A, B. & C
Explanation
The third law states that the entropy of a perfect crystalline substance approaches zero as temperature approaches absolute zero. Entropy generally depends on both temperature and pressure, so options A and B are not correct.
