introduction to the thermodynamics of materials
One mole of copper at a uniform temperature of 0°C is placed in thermal contact with a second mole of copper which, initially, is at a uniform temperature of 100°C. Calculate the temperature of the 2-mole system, which is contained in an adiabatic enclosure, when thermal equilibrium is attained. Why is the common uniform temperature not exactly 50° C? How much thermal energy is transferred, and how much entropy is produced by the transfer? The constant pressure molar heat capacity of solid copper varies with temperature as
Cp = 22.64 + 6.28×10−3T J/mole K

Answer all Parts Please 4) (Conceptual question) Consider a well-insulated container of total volume V0. (a) Initially, the container is divided into two equal parts, using a very thin partition of negligible thickness. One side is filled with a mole of argon at temperature T0 and pressure P0 whereas the other side is under vacuum. The partition is then suddenly removed and the system is allowed to reach equilibrium. Write an expression for: a. Final T and P b. Change...
