a. In October 1957 the Soviet Union launched the first artificial satellite Sputnik 1. Before launch, Soviet scientists tested many prototype satellites. This is an excerpt from theirnotes about test#37: A 83.60-kg prototype satellite, which started at a temperature of -80.00 C was plunged into a tank of 2.50 x 102 kg of pure water, which started at a temperature of 20.00 C. (The lab set up ensured that no heat would be gained or lost from the water tank testing system during this process.) The final temperature of the water tank and the satellite prototype was 15.00 C. What was the specific heat capacity of the prototype satellite used in test#37? b. The prototype used in test#37 was an alloy of Aluminum (Cal = 0.902 J/gC), Magnesium (CM5 = 1.020 J/gC), andTitanium (CTi = 0.54 J/gC). Which of the three metals was most abundant in the prototype used in test#37? c. In the final version of Sputnik 1 they used far more Aluminum. If the satellite's composition was the only variable that changed, and the scientists repeated the water-tank test described above with the final version of Sputnik 1 would you expect greater or lesser change in the tank water temperature? Why?
