. 5 grams of fat are burned in a calorimeter, raising the temperature of 23 kg of water from 20 deg C to 42 deg C. What is the energy value per kilogram of the fat? b). Consider a bear that hibernates in a small burrow for the winter. The bear enters the burrow having a mass of 300 kg and emerges months later having a mass of 250 kg. Assuming the loss of mass was a loss of fat, how much energy does the bear release to the burrow during hibernation? ( Use the energy value for fat that you found in part a) of the problem.)
