Metabolic activity in the human body releases approximately, Ask an Expert

Academics

Metabolic activity in the human body releases approximately 1.0 x 10^4 kJ of heat per day. Assuming the body is 50 kg of water, how much would the body temperature rise if it were an isolated system? How much water must the body eliminate as perspiration to maintain the normal body temperature (98.6 0F)? Does the result make sense? Explain. The heat of vaporization of water may be taken as 2.41 kJ/g.
