	What You'll Learn in this Lesson In this section, we define the notion of entropy as more than just the "randomness" of a system, and talk about the different situations in which the entropy of a system changes. We also talk about how it relates to the 2nd law of Thermodynamics as well as how to use the table of standard entropies to calculated total the total entropy change for a reaction.
