3. If a breath of air, with a volume of 0.500 L, is drawn into the lungs and comes to thermal equilibrium with the body at 37C while the pressure remains constant, calculate the increase in enthalpy of the air if the initial air temperature is 19C and the pressure is 1.00 atm. At a breathing rate of 12 breaths per minute, how much heat is lost in this fashion in 1 day? (See table 2B.1 on page 49 of the textbook for the heat capacity of air. Assume a constant value of the heat capacity over the temperature range of this problem.)
