1. A block of copper at a temperature of 50 °C is placed in contact with a block of aluminum at a temperature of 45 °C in an insulated container. As a result of a transfer of 2500 J of energy from the copper to the aluminum, the final equilibrium temperature of the two blocks is 48 °C a. What is the approximate change in entropy of the aluminum block? b. What is the approximate change in entropy of the copper block? c. What is the approximate change in entropy of the Universe? d. What is the change in energy of the Universe? Let's see how close our two-level system comes to satisfying the old rule of temperature as the average energy per atom. You will use the Entropy Calculator Excel sheet from class (https://goo.gl/Q4uZ1w) to do this in the following three problems. In each case, use N = 1000 atoms in each of the two interacting systems.
