Assume that you have a large swimming pool with isolated walls which is in contact with air at 10C. To maintain the temperature of the water at a constant 25C, you heat it with a coil which is kept at 400C with an electric current. Which choice represents the correct entropy change for water and the whole system (water air coil)? Briefly explain your choice. Question 5 Answer a. Swater<0, Stotal>0 b. Swater=0, Stotal>0 c.
