Which of the following processes is associated with an increase in entropy?
Freezing of water
Condensation of steam
Sublimation of dry ice
Melting of ice
Show Solution
Copy
Sublimation of dry ice (solid CO2) to gas increases entropy as the gas phase has higher disorder than the solid phase.

Q
Q: Which of the following processes is associated with an increase in entropy?
Solution:
Sublimation of dry ice (solid CO2) to gas increases entropy as the gas phase has higher disorder than the solid phase.
Steps: 5
Show Steps
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.
