You Are Trying to Decide What the Change in Heat $\times$

Multiple Choice

You are trying to decide what the change in heat loss would be if you put a 100 cm $\times$ 150 cm and 5-mm thick glass window in an outside wall.The thickness of the wall is 15 cm.If the thermal conductivities of the glass and wall are 0.90 W/m·K and 0.15 W/m·K respectively,calculate the difference in heat loss through thermal conductivity with and without the window when the outside temperature is -10 ^$\circ$ C and the inside temperature is 15 ^$\circ$ C.

B) 6.7 $\times$ 10³ J/s
C) 5.53 $\times$ 10³ J/s
D) 6.75 $\times$ 10³ J/s
