An aluminum block weighing 28 kg initially at 140°c is brought into contact with a block of iron weighing 36 kg at 60°c 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-k

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
