Entropy And T S Diagram

Entropy

• Mnemonic: “Entropy measures disorder, more ways, more disorder.”

• Concept Map:

       +------------------------+
       | Entropy               |
       +------------------------+
              |
    +-----------+----------+
    | Increased | Decreased |
    +-----------+----------+
           |            |
           V            V
  

  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.”

• Concept Map:

  Heat ——> /——-> Entropy In / / /_____/ temperature

• 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.
