Consider two nearby houses of quite different sizes. At mid-morning on a hot summer day, all the windows are open, and the air inside the houses is at the same temperature as the air outside. The houses are then closed up trapping the air inside. At 4pm, it is found that the temperature of the air inside each house has reached about the same elevated value which is considerably higher than the outside temperature. Discuss the amount of heat that has been added to the air in the houses.
