Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg has a regular volume and is 120 km long, 35 km wide, and 230 m thick. (1) How much heat would be required to melt this iceberg (assumed to be at 0°C) into liquid water at 0°C? (The density of ice is 917 kg/m³. The latent heat of fusion for ice is 33.5x104 J/kg.) (ii) Assume the average annual energy consumption by a developed country in the past years was 9.3 x 10o19 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice is completely melted?

![Occasionally, huge icebergs are found floating on the ocean's currents. Suppose
one such iceberg has a regular volume and is 120 km long, 35 km wide, and
