At what rate is heat lost through a 4.0 m x 4.2 m rectangular glass windowpane that is 0.29 cm thick when the inside temperature is 28.8 C and the outside temperature is 8.8 C? The thermal conductivity for the glass is 0.75 W/(m C). Note that 1.0 cm = 102 m. Please round your answer to the nearest whole number (integer). Equation: The heat conducted during time t through a material of thickness Land cross-sectional area A is: Q= (KAAT)t temperature. k is the thermal conductivity and AT is the change in L Make sure that you convert the thickness L into meter.
