In an experiment, 210 g of aluminum (with a specific heat of 900 J/kg·K) at 100°C is mixed with 48.0 g of water (4186 J/kg·K) at 20°C, with the mixture thermally isolated.
(a) What is the equilibrium temperature?
°C
(b) What is the entropy change of the aluminum?
J/K
(c) What is the entropy change of the water?
(d) What is the entropy change of the aluminum-water system?
