Consider a cold winter day with an air temperature of 5°C and relative humidity of about 20% (moisture content 0.001 gH₂O/g dry air). A person waiting at a bus stop inhales at an average rate of

7 g dry air/min and exhales air saturated with water at body temperature (37°C) and 1 atm. The heat capacity of dry air is 1.05 J/(g°C). Estimate the rate of heat loss by breathing in kcal/hr.
