The molar entropy of rhombic sulfur is 31.80 JK-1mol-1 and that of monoclinic sulfur is 32.6 JK-1mol-1 and the densities are 2.070 gcm-3 and 1.957 gcm-3 respectively all at an initial temperature of 298 K. Rhombic sulfur turns into monoclinic sulfur, Calculate the transition temperature for this change at a pressure of 1 bar.
