A 70 kg student catches the flu, and his body temperature increases from 37 C (98.6 F) to 39 C (102.2 F). A. Knowing that much of the human body is comprised of water, calculate the energy used for this change in temperature, approximating the student to be a big sack of water with a specific heat of 4190 J/(kg C). Express your answer in kJ. B. A more precise number for the specific heat of a mammalian body is 3400 J/(kg C). What is the energy expended using this specific heat?
