Assume the weight of an average adult is 70. kg, and that 420. kJ of heat are evolved per mole of oxygen consumed as a result of
the oxidation of foodstuffs, knowing that the number of moles of O2 inhaled per minutes are 0.02 mol/min. Suppose an adult body were encased in a thermally insulating barrier. If as a result of this barrier all the heat evolved by metabolism of foodstuffs were retained by the body, what would the temperature difference of the body reach after 3 hours
