Suppose that there are two very large reservoirs of water, one at a temperature of 89.0 ∘C and one at a temperature of 11.0 ∘C. These reservoirs are brought into thermal contact long enough for 44170 J of heat to flow from the hot water to the cold water. Assume that the reservoirs are large enough so that the temperatures do not change significantly. What is the total change in entropy, Δ?tot, resulting from this heat exchange between the hot water and the cold water?
