An average human produces about 10 MJ of heat each day throughmetabolic activity. If a human body were an isolated system of mass69 kg with the heat capacity of water(Cp,m = 75.31 J K-1mol-1), what temperature rise would the body experience?
Human bodies are actually open systems, and the main mechanism ofheat loss is through the evaporation of water. What mass of watershould be evaporated each day to maintain constant temperature?
