Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg has a regular volume and is 120 km long, 35 km wide, and 230 m thick. (1) How much heat 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. The latent heat of fusion for ice is 33.5x104 J/kg.) (ii) Assume the average annual energy consumption by a developed country in the past years was 9.3 x 10o19 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice is completely melted?

The atmosphere of the planet Mars is 95.3% carbon dioxide (CO2) and about 0.03% water vapor. The atmospheric pressure is only about 600 Pa, and the surface temperature varies from -30°C to -100°C. The polar ice caps contain both CO2ice and water ice. Could there be liquid CO2 on the surface of Mars? Could there be liquid water? Why or why not? [please answer all questions. thank you]
