What are the signs for the entropy change of the system and surroundings, respectively, for water evaporating at 370ºK, when the system is defined as water?

Question

Quizplus · Accepted Answer

For water evaporating, the entropy of the system (water) increases because the molecules move from a more ordered (liquid) state to a less ordered (gas) state, indicating a positive entropy change. The surroundings lose heat to the system for the phase change, leading to a decrease in the entropy of the surroundings, indicating a negative entropy change.
