How many years would it take before the ice melted?

  1. Dec 1, 2006 #1
    1. The problem statement, all variables and given/known data
    Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 149 km long, 27.7 km wide, and 152 m thick. (a) How much heat in joules 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. (b) The annual energy consumption by the United States in 1994 was 9.3 x 1019 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice melted?


    2. Relevant equations
    heat required = mass of ice x heat of fusion for ice
    mass of water is found from density and volume of ice
    density of ice=mass of ice/volume of ice


    3. The attempt at a solution

    a very large number not worth mentioning b/c its not right!

    We have no idea why your number is wrong if you do not show us how you calculated it.
