There are many examples in the chemical world of changes in entropy. Phase transitions are one obvious example. When a substance makes a transition from the liquid state to the gaseous state, the particles have many more possible arrangements, because they are no longer confined to a specified volume in which they are close to each other; gas particles can move freely throughout their container. Vaporization represents an increase in entropy. In the opposite direction, a liquid loses entropy when it freezes to a solid. Because solids have very ordered structures, there are fewer possible arrangements of particles that would result in the properties associated with a solid.
George is going camping and forgot to bring water with him. He decides to collect water from a nearby stream and boil it to make it safe for drinking.
Based on the above, answer the following question:
Given George removes the water from the fire to let it cool down so he can drink it, will the entropy increase or decrease?
