alleryStart learning →A perfect crystal at 0 K has W equal to 1, which makes its entropy:
AThe maximum possible
BLarger than a gas
CImpossible to define
DThe minimum possible
Answer & Solution
Correct answer: D. The minimum possible
1. Entropy follows the count of microstates.
2. Entropy is related to the number of microstates, W, possible for the system.
3. The perfect crystal at absolute zero is described by a single microstate, W equals 1.
4. One is the smallest possible count of microstates.
5. So the entropy of that crystal is the minimum possible.
