Two copper blocks, each of mass 1.25 kg, one at 54°C and the other at 0eC, are placed in contact in an isolated container (so no heat can escape) and allowed to come to equilibrium. Calculate the final temperature of the two blocks (in K), the entropy change of each (in נ-K 1), and AStot (in נ-K 1). The specific heat capacity of copper is 0.3853-K 1-g 1 and may be assumed constant over the temperature range involved final temperature...
