A glass window in a house has an area of 0.67 m^2 and a thickness of 2.4 mm. The temperature inside the house is 21 C, and the outside temperature is 0 C. How much heat is lost through the window in 1 hour (3600 s) due to conduction? Use 1.0 W/(m x C) for the thermal conductivity of the glass. How much heat is lsot through the window in 1 hour (3600 s) due to raditaion? ( assume the temperature of the rntire glass is 21 C for this probelem). Which mode of heat transfer (condutciton vs. raditiaon) accounts for the greater amount of heat loss?
