Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate delta H and Delta Stot when two iron blocks, each of mass 1.00 kg one at 200 deg C and the other at 25 deg C are placed in contact in an isolated container. The specific heat capacity of iron is 0.449 J K^-1 g^-1 and may be assumed constant oer the temperatue range involved.
