Alarge room in a house holds 947 kg of dry air at 33.2°c. a woman opens a window briefly and a cool breeze brings in an additional 62.4 kg of dry air at 13.2°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
