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 the windows transfer heat by conduction, calculate the rate of conduction in watts through a $3.00 {m}^{2}$ window that is 0.635 cm thick (1/4 in) if the temperatures of the inner and outer surfaces are $5.00^{\circ} {C}$ and $-10.0^{\circ} {C},$ respectively. This rapid rate will not be maintained—the inner surface will cool, and even result in frost formation.

The rate of heat conduction is $5.95 \times 10^{3} \mathrm{W}$

to solve this question. We're going to use the formula. Hey, transferred rate is equal to K times eight times difference in temperature, divided by thickness. So okay is constant for each. Material for glass it's appointed for area has given us three meter square. Difference in temperature is 15. Since it's a difference, we can keep them and second degree sensors on the value of D, which is a sickness off a window. It's 150.635 centimeters, so we must convert it to meters. So if you do this calculation, you will get demanding. Five 952 0.8. This is in terms of what and since all values in the questions is given in terms off three significant digits. Let's convert this to three significant bigots. 5.95 times 10 Power three. What's
