Current Attempt in Progress Ice has formed on a shallow pond, and a steady state has been reached, with the air above the ice at -8.6 C and the bottom of the pond at 4.20C. If the total depth of ice + water is 1.8 m, how thick is the ice? (Assume that the thermal conductivityes of ice and water are 0.40 and 0.12 cal/m.Co.s, respectively.)
