### Changes in Entropy

Is there a preferred way to describe a change in entropy of a system? Rather than just saying the amount of disorder within the system has increased or decreased how can we be more specific in this description?

### Re: Changes in Entropy

I believe that it is acceptable to express entropy as disorder as you have described in your post. However, Professor Lavelle also said mentioned that as entropy increases, the amount of possible positions a molecule can occupy also increases, which is why we say that the overall disorder of the system increases.

Entropy is a measure of the number of potential microstates/orientations something could be in. Therefore changes in entropy are changes in the number and position of possible microstates.
