2 kg of stainless steel (aka "Iron, 304") is forged at 1150 C, and then cooled by immersing the steel in 5 kg of water at atmospheric pressure and 20 C. The steel remains in the water until they reach uniform temperature. Assume constant specific heats and neglect any external heat transfer as well as any water that vaporizes during the process
a. What is the final tmperature?
b. What is the change in total entropy (steel water) during this process?
c. Assuming the final temp from part a, what is the % error in entropy change for the water only associated with using constant specific heat?
