Question:

A 10 kg copper block has an initial temperature of 800 K. It is placed in a well-insulated vessel containing 100 kg of water initially at 290 K. The process is isobaric at atmospheric pressure. Assume copper and liquid water have constant heat capacity of CP = 4.184 J/g · K for water and 0.398 J/g · K for copper.

A. When the system reaches equilibrium will be the temperature of the block?

B. What is the change in entropy of the universe resulting from the process?
