Methanol has a molar enthalpy of vaporization of 35.3 kJ mol⁻¹ and a molar enthalpy of fusion of 3.21 kJ mol⁻¹. For a 30.0 g sample of methanol, determine the heat released by condensing the vapor at its boiling point and by freezing the liquid at its melting point, then state which transition releases more energy.
