A large room in a house holds 975 kg of dry air at 30.0C. A woman opens a window briefly and a cool breeze brings in an additional 50.0 kg of dry air at 18.0C. At what temperature will the two air masses come into thermal equilibrium, assuming they form a closed system? (The specific heat of dry air is 1 006 J/kg C, although that value will cancel out of the calorimetry equation.)

The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it To see just how rapidly the windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.00-m2 window that is 0.634 cm thick (1/4 in.) if the temperatures of the inner and outer surfaces are 5.00 and 10.0 , respectively. (This rapid rate will not be maintained—the inner surface will cool, even to the point of frost formation.)
