Table 16.1 lists the energy that can be extracted from various foods, and Table 16.2 gives the rate at which work is done and heat is generated by a person engaged in various activities. Use these data to analyze the following cases.

(a) How much heat energy is generated during a normal night (8 h) of sleep? How many apples must a person consume to compensate for this energy loss? (Round to the next highest whole number.)

(b) What is the total energy expended when a person runs for 30 min at a moderate pace? How many soft drinks does this energy correspond to? (Round to the next highest whole number.)

(c) What is the total energy expended when an elite cyclist races for 6 h at a rapid pace (i.e., at the Tour de France bicycle race)? How many hamburgers does this energy correspond to? (Round to the next highest whole number.)
