The rate of heat conduction out of a window on a winter day israpid enough to chill the air next to it. To see just how rapidlywindows conduct heat, calculate the rate of conduction in wattsthrough a 2.82 m2 window that is 0.755 cm thick if the temperaturesof the inner and outer surfaces are 5.00°C and −10.0°C,respectively. This rapid rate will not be maintained — the innersurface will cool, and frost may even form. The thermalconductivity of glass is 0.84 J/(s · m · °C).
