The correct statement regarding entropy is,
- A At absolute zero temperature, entropy of a perfectly crystalline solid is zero.
- B At absolute zero temperature, the entropy of a perfectly crystalline substance is \( +V e \).
- C At absolute zero temperature, the entropy of all crystalline substances is zero.
- D At \( 0{ }^{\circ} \mathrm{C} \), the entropy of a perfect crystalline solid is zero.
Answer & Solution
Correct Answer
(A) At absolute zero temperature, entropy of a perfectly crystalline solid is zero.
Step-by-step Solution
Detailed explanation
The correct statement regarding entropy is at absolute zero temperature (i.e., \( -273.15^{\circ} \mathrm{C} \) or \( 0 \mathrm{~K} \) ) entropy of a perfectly
crystalline solid is zero.
crystalline solid is zero.
