State cesium solidifies to cs(s) at its normal melting point

Reference no: EM13520738

The element cesium (Cs) freezes at 28.4 degrees C, and its molar enthalpy heat of fusion is (triangle)Hfus = 2.09kJ/mol.

a.) When molten cesium solidifies to Cs(s) at its normal melting point, is (triangle)S positive or negative?

b.) Calculate the value of (triangle)Stotal when 15.0g of Cs(l) solidifies at 28.4 degrees C.
