Following vigorous exercise, the body temperature of a 65.0 kg person is 39.7°C . At what rate in watts must the person transfer thermal energy to reduce the the body temperature to 37.0°C in 24.0 min, assuming the body continues to produce energy at the rate of 150 W? (1 watt = 1 joule/second or 1 W = 1 J/s). (Assume that the specific heat of a human is chuman = 3,500 J/(kg · °C).)
