1. The problem statement, all variables and given/known data The ice cap on the North Pole could be 1000 m thick with a density of 920 kg/m3. Find the pressure at the bottom and the corresponding melting temperature. 2. Relevant equations Steam tables ΔP = ρgH 3. The attempt at a solution ΔP = (920 kg/m3)*(9.28 m/s2)*(1000) = 9022 kPa P = Pinitial + 9022 kPa I have no idea how to find initial pressure, which I think is my main information missing, then from there I would need to find the corresponding temperature.
