In an experiment, 99.0 g of aluminum (with a specific heat of 900 J/kg·K) at 93.0°C is mixed with 88.0 g of water (with a specific heat of 4186 J/kg·K) at 32.0°C, with the mixture thermally isolated.
(a) What is the equilibrium temperature, in Celsius? What are the entropy changes of
(b) the aluminum,
(c) the water, and
(d) the aluminum-water system?
