1. the “global maximum” value of our data set is approximately 6.9 million square kilometers. this maximum occurred in 1980. the “global minimum” value of our data set is approximately 3.6 million square kilometers, recorded in 2007. from this data calculate the area lost from 1980 to 2007. what landmass can you compare this area lost to? example park, planet, state, country etc. 2. using density = mass/volume and volume = (area) (thickness), calculate the mass of ice that was lost during this time period. the density of ice is 1000 kg/m^3. assume a uniform density. the average ice thickness for the arctic/greenland region was 2.5 meters. for this problem, you will need to make several calculations. a. you will need to convert your thickness unit from meters to km using factor label method/dimensional analysis (do not just move decimal show conversion ratio b. calculate volume c. convert your km3 to m3 using factor label method/dimensional analysis with correct ratio. d. calculate mass 3. calculate how much energy was required to melt the ice change in energy ∆h = (mass)(heat of fusion) the heat of fusion for ice is 334 kj/kg. 4. using your calculated value for mass from number 2 restate your results in pounds. as an example, a 54.5 kg person would weigh about 120 pounds on earth.
