# Summary
|
|
* Entropy describes energy's tendency to spread out and cause some of the energy to become useless.
|
|
* Entropy decreases when energy is organized, increases when spread out.
|
|
* Higher entropy means more useless energy.
|
|
* Total entropy of an isolated system never decreases over time.
|
|
* Entropy remains constant only in perfectly reversible processes (theoretical).
|
|
* IRL, entropy always increases. |
