Suppose one such iceberg is 131 km long, 37.7 km wide, and 211 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°C? The density of ice is 917 kg/m), (b) The annual energy consumption by the United States in 1994 was 9.3 x 1019 3, lf this energy were delivered to the iceberg every year, how many years would it take before the ice 002 012 034 043 051 (a) Number (b) Number Click if you would like to Show Work for this question: Question Attempts: O of 5 used SAVE FOR LATER Review Score Objective Copyright © 2000-2015 by John Wiley & Sons, Inc. or related companies Al rights reserved. version 4.162.2Explanation / Answer
From the given data
Mass of ice is given by =Density of ice*Volume of ice =917*131*103*37.7*103*211 =955.574*1012kg
The heat required for the mass is =Mass of ice*Lf =955.574*1012kg*335000 =320.117*1018J
now the time required to melt this ice is =320.117*1018J/conusmption energy 9.3*1019 =34.42 *10-1yrs =3.442syears
