The potential energy increases. The evaporation decreases. The disorder decreases. The entropy increases.
I gave my students this multiple choice question: Water at 20 degrees Celsius is placed on a stove. As the water is heated, thermal energy is absorbed by the water. If the water is heated to a maximum temperature of 80 degrees Celsius, what happens as a result of the increased temperature?

Only one answer is correct among these 4 choices:
- The potential energy increases.
- The evaporation decreases.
- The disorder decreases.
- The entropy increases.

Could you tell me which one is correct?

The entropy increases.
