An aluminum block weighing 32 kg initially at 140°C is brought into contact with a block of iron weighing 44 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 Cp0.949 kJ/kg.K. The specific heat of iron at room temperature is Cp=0.45 kJ/kg.K. The final equilibrium temperature is 108,35 K. The total entropy change for this process is 397 kJ/K

Use the exact values you enter in previous answer(s) to make later calculation(s). A block of copper at a temperature of 54 degree C is placed in contact with a block of aluminum at a temperature of 44 degree C in an insulated container. As a result of a transfer of 1085 J of energy from the copper to the aluminum, the final equilibrium temperature of the two blocks is 48 degree C. What is the approximate change in the...
