Question

Melting Iceberg lcebergs In the North Atlantic present hazards to shipping, causing the length o shipping mutes to increase by at ut 30% during the ice e season. Attempts to de l eher s in de pan ng expos e bombi torpedoing, shelling a m ing and painting with lamp lack. Suppose that direct melting o the ice rg, by placing heat sources in the ice i tri Ho much heat is equired to melt 13.0% o 2.70×10 metric ton iceberg? One metric ton is equal to 108 kg. Assume that the iceberg is at -4.00°C. Specific heat of ice is 2050 J/(kg.K). (Note: To appreciate the magnitude of this energy, cormpare your answer to the Hiroshirma atomic bomb which had an energy equivalent to about 15,000 tons of TNT, representing an energy of about 6.0×1013 .) 1.17 10 1.17-10-13 Submit Answer Incorrect.
