ng becomes wet. She is packing emergency rations that if com- pletely metabolized will release 35 kJ of heat per gram of ration: consumed. How much rations must the hiker consume to avoid reduction in body temperature of 2.5 K as a result of heat loss? Assume the heat capacity of the body equals that of water and that the hiker weighs 51 kg. State any additional assumptions.
