In 1986, a gargantuan iceberg broke away from the Ross Ice Shelf in Antarctica. It was approximately a rectangle 160 km long, 40.0 km wide, and 250 m thick. (a) What is the mass of this iceberg, given that the density of ice is 917 kg/m^3? (b) How much heat transfer (in joules) is needed to melt it and reach 30 degrees Celsius (c) How many years would it take sunlight alone to melt ice, if the ice absorbs an average of 100 W/m^2 from sunlight on half its surface area, 12.00 h per day?
