Two copper blocks, each of mass 5.0 kg, one at 80 C and the other at 10 C are placed in contact in an isolated container. The specific heat capacity of for copper for 0.385 J/ K*g and maybe assumed constant over the temperature from 0 C to 100 C. First estimate the sign of (delta)H hot, (delta) H cold, (delta) H total, (delta) S hot, (delta)S cold, (delta) S total, respectively, and then determine the numerical values for them the subscript hot, cold, and total stands for the hot brick, the cold brick and the sum of the two.
