MSE 3050, Phase Diagrams and Kinetics, Leonid Zhigilei homework #2 (page 1 or 2) 1. One mole of copper at a uniform temperature of 0ºC is placed in thermal contact with a second mole of copper which, initially, is at a uniform temperature of 100ºC. The pressure in the system is maintained at 1 atm. The two moles of copper are thermally insulated from the surroundings. Temperature dependence of the constant pressure heat capacity of solid copper can be described by C p = 33.64 + 6.28 × 10 -3 T J/mole K. (a) Calculate the common temperature of the 2 mole system, which is contained in an adiabatic enclosure, when thermal equilibrium is attained. (b) How much heat is transferred between the two parts of the system? (c) How much entropy is produced by the transfer? 2. Consider a small cube of silver enclosed in a reservoir so large that small transfer of heat to silver does not change its temperature, 1400 K. Calculate the
