Calculate the entropy change for the conversion of 1 mole of ice of 274 K and 1 atm into steam at 350 K and 1 atm. Assume constant pressure within this temperature. Given, the molar heat of fusion of ice= 7 kj per mol, the molar heat of vaporisation of water= 42 kj per mol,and heat capacity at constant pressure = 76 j per k per mol.
