An average man weighs about 70 kg and produces about 10460 kJ of heat per day. Suppose that a man was an isolated system and that his heat capacity was 4.18 J/Kg; if his temperature were 37ºC at a given time, what would be his temperature 24 h later? A man is in fact in an open system, and the main mechanism maintaining his temperature constant is evaporation of water. If the enthalpy of vaporization of water at 37ºC is 43.4 kJ/mol, how much water needs to be evaporated per day to keep the temperature constant?PROVIDE DETAILED SOLUTION ON LETTER B.
