Question $3($Mandatory$)(1$ point$)$ 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 $3\mathrm{.}0-$m$2$ window that is $0\mathrm{.}635$ cm thick $(1/4$ in$)$ if the temperatures of the inner and outer surfaces are $5\mathrm{.}0$C and $10\mathrm{.}0$C $,$ respectively. This rapid rate will not be maintained$$the inner surface will cool, and even result in frost formation. Question $3$ options: a$)600$ W b$)1\mathrm{.}2$ kW c$)3\mathrm{.}6$ kW d$)6\mathrm{.}0$ kW
