An aluminum block weighing 34 kg initially at 140°c is brought into contact with a block of iron weighing 48 kg at 60c in an insulated enclosure. determine the final equilibrium temperature and the total entropy change for this process. the specific heat of aluminum at 400 k is cp 0.949 kj/kg k. the specific heat of iron at room temperature is cp 0.45 kj/kg a)-the final equilibrium temperature is k b)-the total entropy change for this process /k.
