## Entropy Definition [ENDORSED]

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Entropy Definition

In class, Dr. Lavelle avoided using the word "disorder" to describe entropy but the book consistently uses it. How would we define/what was Dr. Lavelle's definition of entropy without using "disorder"?

### Re: Entropy Definition

You can think of entropy as energy dispersion or degeneracy.

### Re: Entropy Definition  [ENDORSED]

We can do this by using Degeneracy and as well as the fact that states of matter can “occupy” more positions when that matter has more entropy. For example, a substance in the gas phase has more entropy and thus can occupy more “positions” than a substance in the solid phase.
