Which of the following processes is associated with an increase in entropy?
Correct Answer: Sublimation of dry ice (solid CO2) to gas
- Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
- Step 2: Identify the states of matter: solid, liquid, and gas. Solids are more ordered, while gases are more disordered.
- Step 3: Look at the process mentioned: sublimation of dry ice (solid CO2) to gas.
- Step 4: Recognize that when dry ice (solid) turns into gas, it goes from a more ordered state (solid) to a less ordered state (gas).
- Step 5: Conclude that this change from solid to gas increases the disorder of the system, which means entropy increases.
