The correct statement regarding entropy is,

Options

  1. AAt absolute zero temperature, entropy of a perfectly crystalline solid is zero.
  2. BAt absolute zero temperature, the entropy of a perfectly crystalline substance is ( +V e ).
  3. CAt absolute zero temperature, the entropy of all crystalline substances is zero.
  4. DAt ( 0 ^ C ), the entropy of a perfect crystalline solid is zero.

Correct answer

A. At absolute zero temperature, entropy of a perfectly crystalline solid is zero.

Step-by-step solution

The correct statement regarding entropy is at absolute zero temperature (i.e., ( -273.15^ C ) or ( 0 ~K ) ) entropy of a perfectly crystalline solid is zero.
