A glass of water contains a teaspoon of dissolved sugar.

Chapter 15, Problem 15.38

(choose chapter or problem)

A glass of water contains a teaspoon of dissolved sugar. After a while, the water evaporates, leaving behind sugar crystals. The entropy of the sugar crystals is less than the entropy of the dissolved sugar because the sugar crystals are in a more ordered state. Why doesnt this process violate the second law of thermodynamics? (a) Because, considering what happens to the water, the total entropy of the universe also decreases. (b) Because, considering what happens to the water, the total entropy of the universe increases. (c) Because the second law does not apply to this situation.
