3.34 a) Body temperature is 37oC. From Appendix A.III, ice at 0oC has a volume of 0.0010908 m3/kg and an enthalpy (and internal energy) of -333.43 kJ/kg. For water at 35oC = 146.67 kJ/kg and at 40ˆUoC = 167.56 kJ/kg, so that at 37ˆUoC ˆU = 155.03 kJ/kg. Also, 1 L = 10-3m3, so that 1 L of water 10-3m3/0.0010908 m3/kg = 0.9168 kg. So that the amount of energy needed to melt 1 L of ice is
