question 102

Multiple Choice

A 300 kg black bear hibernates in the winter. During hibernation the bear's body temperature drops from 37 to 31°C. How many grams of glucose must the bear metabolize to restore its body temperature to normal? Assume the bear's body is mostly water with a specific heat capacity of 4.2 J/(g . °C) and that all the energy from the combustion of glucose is used to raise the bear's body temperature. (Glucose: $\Delta$ H(combustion) = -2,830 kJ/mol, molar mass = 180 g/mol)

• A) 7,560 g
• B) 2.67 g
• C) 2,975 g
• D) 481 g
• E) 16.5 g
