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

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine
