Why does the third law apply only to pure crystalline solids?
AGases have no entropy at all
BLiquids are perfectly ordered
CLiquids keep some entropy at 0 K
DCrystals show no real order
Answer & Solution
Correct answer: C. Liquids keep some entropy at 0 K
Only a perfect crystal has perfect order at 0 K, while solutions and supercooled liquids retain disorder.
