If a single pane glass window on a house has an area of 0.5 m^2 and is 3mm thick, what is rate of heat loss through this window on a cold winter day when the inside surface of the glass is 15?C and the outside surface is 5?C? Assume the glass has k=2.0 W/m-K. (b) How much can the heat loss be reduced if the window is constructed to be double-pane (2 mm per pane) with a 5mm Argon filled spaced between the panes (assume the same temperature difference and a value of k=0.016W/m-K for Argon)
