When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37.0°C) by warming up the water in your stomach. Could drinking ice water, then, substitute for exercise as a way to "burn calories?" Suppose you expend 490. kilocalories during a brisk hour-long walk. How many liters of ice water (0°C) would you have to drink in order to use up 490. kilocalories of metabolic energy? For comparison, the stomach can hold about...

Each pound of fat contains 3500 food calories. When the body
metabolizes food, 80.5% of this energy goes to heat. Suppose you
decide to run without stopping, an activity that produces 1340 W of
metabolic power for a typical person.
Part A) For how many hours must you run to burn up 1 lb of
fat?
Part B) If you followed your planned exercise program, how much
heat would your body produce when you burn up a pound of fat?...
