Question
(a) What is the temperature increase of an 80.0 kg person who consumes 2500 kcal of food in one day with 95.0% of the energy transferred as heat to the body? (b) What is unreasonable about this result? (c) Which premise or assumption is responsible?
1. $35.5\textrm{ C}^\circ$
2. Body temperature is highly regulated within a narrow range about $37^\circ\textrm{C}$. A temperature increase greater than $3 \textrm{ C}^\circ$ is life threatening.
3. It's unreasonable to presume that 95% of heat generated from food will be retained by the body. The body has mechanisms, such as sweating, to dissipate heat.
