A Thermodynamic Process in a Solid. A cube of copper 2.00 cm on a side is suspended by a string. (The physical properties of copper are given in Tables 14.1, 17.2, and 17.3.) The cube is heated with a burner from 20.0oC to 90.0oC. The air surrounding the cube is at atmospheric pressure (1.01 X 105 Pa). Find
(a) The increase in volume of the cube;
(b) The mechanical work done by the cube to expand against the pressure of the surrounding air;
(c) The amount of heat added to the cube;
(d) The change in internal energy of the cube.
(e) Based on your results, explain whether there is any substantial difference between the specific heat capacities Cp (at constant pressure) and Cv (at constant volume) for copper under these conditions.
