Question

The heat required to sustain animals that hibernate comes from the biochemical combustion of fatty acids, such as arachidonic acid, C20H32O2. Assume that the heat required to raise the body temperature of a hibernating animal is provided by the combustion of C20H32O2 and that the oxygen required by the reaction comes from the air that the animal breathes in. Calculate the work done (w), when one mole of C20H32O2 is burned at constant pressure (1 atm) at 25 Degree C. Also, calculate the constant volume heat of combustion (qV), in kilojoules per mole, for arachidonic acid. Calculate delta H0t for arachidonic acid. Calculate the mass of arachidonic acid a 400-kg bear must "bum" and the minimum volume of air, measured at 5.00 Degree C and 101 kPa, that the bear must breathe in to raise its body temperature from 5.00 Degree C to 25.0 Degree C.
