Consider a glass window pane that has the following properties:
Density: 2300 kg m
-3
Specific heat: 840 J kg
-1 ?C
-1
Coefficient of linear thermal expansion: 8.5 × 10-6 ?C
-1
Thermal conductivity: 0.80W m
-1 ?C
-1
Colour: a pretty shade of blue.
The
The pane is 1.8m high, 1.5m wide, and 8.0mm thick. If the temperature at the inner surface of the glass is 28?C and that at the outer surface 4.0 ?C, and the heat transfer is in a steady state, how much heat is lost by conduction through the window each hour?
