One mol of aluminum at a uniform temp of 0C is placed in thermal contact with a 2nd mol of aluminum which, initially is at a uniform temp of 200C. The pressure in the system is maintained at 1 atm. The two moles of aluminum are thermally insulated from the surroundings. Temperature dependence of the constant pressure heat capacity of solid aluminum can be described by the following expression: Cp= 20.67 + 12.38*10^-3 T J/mol K

a) Calculate the common temp of the two mol system which is contained in an adiabatic enclosure, when the thermal equilibrium is attained.

I found that it was 102.446 C is that correct?

b)How much heat is transferred between the two parts of the system?

C) How much entropy is produced by the transfer?
