Compare, i$.$e$.,$ find the ratio of the rate of heat conduction through a $14\mathrm{.}0$cm$$thick wall that has an area of $10\mathrm{.}0$ m$2$ and a thermal conductivity twice that of glass wool with the rate of heat conduction through a window that is $0\mathrm{.}750$ cm thick and that has an area of $2\mathrm{.}40$ m$2,$ assuming the same temperature difference across each.
