A tank of water has been outdoors in cold weather, and a slabof ice 5.0 cm thick has formed on its surface. The air abovethe ice is at -10°C .
Calculate the rate of ice formation (in cm per hour) on theice slab. Take the termal conductivity of ice to be 0.004 calscmC and its density to be 0.92g/cm3. Assume no energy transfer through the tank wallsor bottom.
Anwswer is 0.4 cm/h

Okay, first off we are missing a piece of information. The amount of energy that has to be transferred from water beforeit becomes ice, namely the heat of fusion Hf Theheat of fusion for water is
P=dQdt=KiceA(ThTc)z
Okay now we need to talk about the equations we want to usefor this problem. We have heat transfer, so well
