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

(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.
