157 grams of aluminum at 367 degrees Kelvin is placed in a well insulated cup with 2.3 kilograms of water at 299 degrees Kelvin. What is the increase in the system's entropy (in J/K) by the time it reaches equilibrium temperature? The specific heat capacity of water is 4200 J/Kg/K and of the aluminum is 900 J/Kg/K.
