When glucose, a sugar, reacts fully with oxygen, carbon dioxide and water are produced: C,H12O6(s) + 6 O2(g) → 6 CO2(g) + 6 H,O(€) AH° = -2820 kJ Suppose a person weighing 50 kg (mostly water, with spe- cific heat capacity 4.18 J K-1 g¯') eats a candy bar con- taining 14.3 g glucose. If all the glucose reacted with oxygen and the heat produced were used entirely to increase the person's body temperature, what temperature increase would result? (In fact, most of the heat produced is lost to the surroundings before such a temperature increase occurs.)
