Question

A large room in a house holds 927 kg of dry air at 31.2°C. A woman opens a window briefly and a cool breeze brings in an additional 60.4 kg of dry air at 14.2°C. At what temperature (in degrees Celsius) will the two air masses come into thermal equilibrium, assuming they form a closed system? (The specific heat of dry air is 1006 J/ kg * °C, although that value will cancel out of the calorimetry equation.)

°C
