Occasionally, huge icebergs are found floating on the ocean'scurrents. Suppose one such iceberg is 124 km long, 41.5 km wide,and 217 m thick.
(a) How much heat in joules would be requiredto melt this iceberg (assumed to be at 0°C) into liquid water at0°C? The density of ice is 917 kg/m3 and the latent heatof fusion is 334 kJ/kg.
(b) The annual energy consumption for Australiain the 2017-2018 financial year was 6.172×1018 J. Ifthis energy was delivered to the iceberg every year, how many yearswould it take before the ice melted?
