Question

Suppose a house's walls are 14.5 cm thick and and have an average thermal conductivity twice that of glass wool.

Part (a)  Calculate the rate of heat conduction, in watts, through the house's walls. Assume there are no windows or doors. The surface area of the walls is 125 m2 and their inside surface is at 19.5°C, while their outside surface is at 4.95°C . 

Part (b)  How many 1.00-kW room heaters would be needed to balance the heat transfer due to conduction? Round your answer to the nearest integer value.
