Since the aluminum bar is not an isolated system, the second law of thermodynamics cannot be applied to the bar alone. rather, it should be applied to the bar in combination with its surroundings (the lake). assume that the entropy change of the bar is -1238 j/k . what is the change in total entropy δstotal?
