Answer #1

Let the rate of heat flow is .

The area of the glass A=1.031.71 m2.

The thickness of the glass d=3.34 mm.

The thermal conductivity of window glass is k=1 W/m.k.

The temperature difference is

  

   The rate of heat flow

     

The rate of heat flow is 6064.356287 W.

[ I took k=1 W/m.k, if needed I will update answer please provide me the value of k]

    The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly windows conduct heat, calculate the rate of conduction in watts through a 2.72 m2 window that is 0.515 cm thick if the temperatures of the inner and outer surfaces are 5.00°C and −10.0°C, respectively. This rapid rate will not be maintained — the inner surface will cool, and frost may even form....
