In an experiment, 300 g of aluminum (specific heat of 900J/kg*K) at 120 Celsius is mixed with 60 g of water at 20 Celsius,with the mixture thermally isolated. You will need to look up thespecific heat of water. (a) What is the equilibrium temperature?(b) What is the entropy change for the aluminum block? (c) What isthe entropy change for the water? (d) What is the entropy changefor the aluminum-water system?
