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

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
Temple University Fox School of Business ‘17, Course Hero Intern
I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
University of Pennsylvania ‘17, Course Hero Intern
The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
