A cylinder made of brass with a mass of 0.80 kg is heated to 800°C, then dropped into 7.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the cylinder-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of brass is 380 3/(kg K), and the specific heat of water is 4,186 J/(kg K). (Hint: note that dQ = mcdT.) J/K
