title: Monoclinic Sulfur: Heat Capacity Anomaly at 198{degrees}K Caused by Disordering of the Crystal Structure.
abstract: The entropy of disorder of the idealized crystal structure of monoclinic sulfur at high temperatures is equal to the extra entropy change in the lambda-type (second order transformation type) heat capacity anomaly found at 198 degrees K. The extrapolated entropy is zero at 0 degrees K. The partially disordered crystal structure gradually becomes ordered as the temperature is lowered.
