Instrumental. The Mettler TA2000B thermal analysis system is equipped with an interface system, and Hewlett-Packard 9815 desk top calculator and 7225 plotter. Samples, weighing 5-10 mg, sealed in aluminum pans and under a nitrogen blanket, were heated in the calorimeter at a rate of 10 deg/min from -35 or 10 deg C to 180 deg C respectively, for specific heat and kinetic scans. Specific heat measurements were calibrated with alumina to an accuracy of 3%. Temperatures and enthalpies were calibrated with an Indium sample. The accuracies were .02 deg C and 2% (Indium 28.5 J/g), respectively. 

C is correct. Aluminum has the largest value for specific heat, which means that it can absorb the most energy while showing the smallest temperature change.

The specific heat of aluminum is 0.903 J/g°C that of copper is 0.385 J/g°C. Suppose you have one cube each of A1 and Cu both cubes have a mass of 100 g and are at a temperature of 100°C. Which cube will release more heat when it cools to 20°C ... 

Alumimun is the metal of choice for soft-drink cans, as shown in Figure 20.11. It is lightweight, has a low specific heat (0.902 J/g°C), and conducts heat rapidly. As a result of its low specific heat, the aluminum itself absorbs litde heat, so the beverage inside the container can be cooled quickly. In Chapter 17, you learned that aluminum is produced by electrolysis of its principal ore, bauxite. The production of aluminum requires large amounts of energy, particularly electrical energy. Therefore, one...
