(a) Calculate the rate of heat conduction (in W) through house walls that are 11.5 cm thick and that have an average thermal conductivity twice that of glass wool. Assume there are no windows or doors. The surface area of the walls is 150 m2 and their inside surface is at 20.0°C, while their outside surface is at 5.00°C.   Answer _________ W (NO scientific notation ONLY Real Number)    (b) How many 1 kW room heaters would be needed to balance the heat transfer due to conduction? (Round your answer to the next whole integer.)   Answer__________ 1 kW room heaters (NO scientific notation ONLY Real Number)

(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a 1.40-m2 surface area? Assume that the animal’s skin temperature is 32.0 °C , that the air temperature is −5.00 °C , and thatfur has the same thermal conductivity as air. (b) What food intake will the animal need in one day to replace this heat transfer?
