A rod made of copper with a mass of 0.90 kg is heated to 850°C, then dropped into 5.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the rod-water system, assuming no energyis last by heat from this system to the surroundings? The specific heat of copper is 387 J/(kg K), and the specific heat of water is 4,186 J/(kg K). (Hint: note that dQ = mcdT.)X555First, consider conservation of energy. Using the specific heats, can you find the final equilibrium temperature of the combined system? Next consider the infinitesimal change in entropy ds. How doesit depend on dQ and temperature? Note the expression given for dQ in the hint. Can you write an infinitesimal expression for each object that can be integrated from the initial to final temperature?J/K
