Question

Icebergs in the North Atlantic present hazards to shipping,causing the length of shipping routes to increase by about 30percent during the iceberg season. Attempts to destroy icebergsinclude planting explosives, bombing, torpedoing, shelling,ramming, and painting with lampblack. Suppose that direct meltingof the iceberg, by placing heat sources in the ice, is tried. Howmuch heat is required to melt 11 percent of a3.10×105 metric-ton iceberg? One metric ton isequal to 103 kg. Assume that the iceberg is at 0°C.(Note: To appreciate the magnitude of this energy, compareyour answer to the Hiroshima atomic bomb which had an energyequivalent to about 15,000 tons of TNT, representing an energy ofabout 6.0×1013 J.) im doing (weight in tons)(1000)(your %)(heat of fusion ofwater
in Joules which is 333000) ...still wrong what am i missing??

Explanation / Answer

0.11 *(3e5 metric tons) *(1000 kg/1metric ton) *(1000 g/1kg)*(333.55 J/g) = 1.10 x 1013 J 333.55 J/g is the latent heat of ice -> water PM me if you have more questions
