3.(10p) The molar volume of a certain solid is 142.0 cm3mol-1 at 1.00 atm and 427.15 K, its melting temperature. The molar volume of the liquid at this temperature and pressure is 152.6 cm3mol-1. At 1.2 MPa, the melting. temperature changes to 429.26K. Calculate the enthalpy and entropy of fusion of the solid using the Clapeyron equation.
