Ice has formed on a shallow pond, and a steady state has been reached, with the air above the ice at -9.6°C and the bottom of the pond at 5.5°C. If the total depth of ice + water is 2.1 m, how thick is the ice? (Assume that the thermal conductivities of ice and water are 0.40 and 0.12 cal/m·C°·s, respectively.)
P = KA(Th - Tc)/L
The Attempt at a Solution
Do I have the right equation for this question? I'm not too sure because I don't have any information related to the area besides depth.
