1. Calculate ΔH and ΔStot when two iron blocks, each with a mass
of 1.00 kg and 4 kg, one at 200°C and the
other at 25°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 over the
temperature range involved.

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...
