arrangements transferred
 Example: When you shuffle a deck of cards, the entropy of the deck increases because there are more possible arrangements of the cards.
TS Diagram
 Mnemonic: “TS diagrams: follow the flow of heat energy with temperature and entropy.”

 Example: When heat is added to a system, the TS diagram shows the change in entropy and temperature. The area under the TS curve represents the heat transferred to the system.
