In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 12.4 oC. The temperature at the inside surface of the wall is 19.9 oC. The wall is 0.16 m thick and has an area of 7.2 m2. Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall?
