Briefly discuss. Note: Cp = 4.185 J/g-K for water and 0.398 J/g-K for copper. Also, assume that the process occurs isobarically.
A copper block having a mass of 10 kg and a temperature of 800 K is placed in a well-insulated vessel containing 100 kg of water initially at 290 K. What will be the final temperature of the block and the entropy changes for the copper, the water, and the universe resulting from the process? Does this number (the entropy change of the universe) “make sense” to you?
