In an experiment, 190 g of aluminum (with a specific heat of 900 J/kg-K) at 53.0°C is mixed with 81.0 g of water (with a specific heat of 4186 J/kg-K) at 13.0°C, with the mixture thermally isolated. (a) What is the equilibrium temperature? What are the entropy changes of (b) the aluminum, (c) the water, and (d) the aluminum-water system?
