the A concrete slab is 10.0 cm thick and has an area of 6.00 m². Electric heating coils are installed under the slab to melt the ice on the surface in winter months. What minimum power must be supplied to the coils to maintain a temperature difference of 19.5°C between the bottom of the slab and its surface? Assume all the energy transferred is through the slab, and the thermal conductivity of the concrete is 1.3 J/s m**C. W
