Entropy And T S Diagram
Entropy
- Mnemonic: “Entropy measures disorder, more ways, more disorder.”

More possible More heat
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.
T-S Diagram
- Mnemonic: “T-S diagrams: follow the flow of heat energy with temperature and entropy.”

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