Following vigorous exercise, the body temperature of an 85.0 kg person is 40.1°C . At what rate in watts must the person transfer thermal energy to reduce the the body temperature to 37.0°C in 22.0 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).

Following vigorous exercise, the body temperature of a 60.0 kg person is 39.9°C . At what rate in watts must the person transfer thermal energy to reduce the the body temperature to 37.0°C in 28.0 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). W
A healthy human body maintains a central core of about 37.0 C (98.6 F) To do so, the body must shed excess thermal energy that is comverted from chemical energy due to metabolic processes. This is especially challenging during vigorous exercise, when the body's care temperature can increase by as much as 6 Cin only 15 min, which can lead to convulsions or even brain damage Energy transfer is the key to maintaining a consistent temperature. We can analyze how...
