(a) At the transition temperature 95.4 C, the heat of transition from rhombic to monoclinic sulfur is 0.09 kcal/mol. Calculate the entropy of transition. (b) At the melting point, 119 C, the heat of fusion of monoclinic sulfur is 0.293 kcal/mol. Calculate the entropy of fusion.

If a || b and e || f, what is the value of y ?
