A glass windowpane in a home is 0.620 cm thick and has dimensionsof 1.17 m 1.60 m. On a certain day, the temperature of the interiorsurface of the glass is 21.0°C and the outdoor temperature is 0°C.Assume the thermal conductivity of the glass is 0.8 W/m · °C.
(a) What is the rate at which energy is transferred by heat throughthe glass?
(b) How much energy is transferred through the window in one day,assuming the temperatures on the surfaces remain constant?
