A hiker caught in a thunderstorm loses heat when her clothingbecomes wet. She is packing emergency rations which if completelymetabolized will release 30kJ of heat per gram of rations consumed.How much rations must the hiker consume to avoid a reduction inbody temperature of 4.0K as a result of heat loss? Assume the heatcapacity of the body equals that of water and that the hiker weighs55kg.
