Identify the correct statement regarding entropy:
  • a)
    At 00C, the entropy of a perfect ly crystalline substance is taken to be zero
  • b)
    At absolute zero of the temperature, the entropy of all perfectly crystalline substance is positive
  • c)
    At absolute zero of the temperature the entropy of all perfectly crystalline substance is taken to be zero
  • d)
    At absolute zero temperature, the entropy of a perfectly crystalline substance is taken to be zero
Correct answer is option 'D'. Can you explain this answer?

Explanation:
Entropy is a measure of the degree of disorder or randomness of a system. The entropy of a perfectly crystalline substance is taken to be zero at 0 K or absolute zero temperature. This is because at absolute zero temperature, the molecules of the substance stop moving and the atoms are arranged in a perfectly ordered crystal lattice, resulting in a state of minimum entropy. At this temperature, there is no energy available for the particles to move and hence no entropy.

Correct Option:
The correct statement regarding entropy is option 'D' - At absolute zero temperature, the entropy of a perfectly crystalline substance is taken to be zero.
