Question
Which law states that the entropy of a perfectly ordered crystalline substance at 0 K is zero?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The Third Law of Thermodynamics states that the entropy of a perfect crystal at absolute zero (0 Kelvin) is zero. This provides an absolute reference point for determining entropy values.
Hint
This law deals with entropy at the lowest possible temperature.
