1. Normal body temperature is 98.6 °F. What is this temperature in °C?
A person with a "fever" has a temperature of 102 °F. How much higher a
temperature, in °C, is this than normal
2. Resting metabolism. Suppose a body loses heat to the environment at the rate of 100 J
/ hr. How long would it take to a resting person to completely convert to energy
(metabolize) a cookie with a nutritional value of 60 Cal.
Suppose the same individual engage in aerobic exercise, during which the body
looses hear to the environment at the rate of 250 J/ hr. How long will it take to
metabolize the energy in a 60 Cal cookie.
3. How much energy must be removed from 200 g of water beginning at 25 "C to
convert it to ice cubes at
