Statement of a problem № 11260


Occasionally, huge icebergs are found floating on the ocean s currents. Suppose one such iceberg is 120 km long, 35 km wide, and 230 m thick. (a) How much heat would be required to melt this iceberg (assumed to be at 0 oC) into liquid water at 0 oC? The density of ice is 917 kg/m3. (b) The annual energy consumption by the United States is about 1.1 × 1020 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice melted?
