A tank of water has been outdoors in cold weather, and a slab of ice 5.0 cm thick has formed on its surface (Figure). The air above the ice is at ?? 10oC. Calculate the rate of ice formation (in centimeters per hour) on the ice slab. Take the thermal conductivity of ice to be 0.0040 cal/s ? cm ? Co and its density to be 0.92 g/cm3. Assume no energy transfer through the tank walls or bottom.
