P4.10 We return to the 58-kg hiker of P4.9, who is climb- ing the 828-m-tall Burj Khalifa in Dubai. If the efficiency of converting the energy content of the bars into the work of climbing is 25%, the remaining 75% of the energy released through metabolism is heat released to her body. She eats two energy bars, one of which produces 1.25 X 10° kJ of energy upon metabolizing. Assume that the heat capacity of her body is equal to that for water. Calculate her temperature at the top of the structure. Is your result reasonable? Can you think of a mechanism by which her body might release energy to avoid a temperature increase?
