Question

in which example is the entropy of the final state greater than the entropy of the initial state? liquid water freezes into ice. bricks are built to form a wall. dry ice (solid co₂) sublimes.

Explanation:

Entropy is a measure of disorder. A process with increasing entropy has more disorder in the final state.

• For "Liquid water freezes into ice", liquid to solid (more ordered) → entropy decreases.
• For "Bricks are built to form a wall", disordered bricks to ordered wall → entropy decreases.
• For "Dry ice (solid \( \text{CO}_2 \)) sublimes", solid to gas (much more disordered) → entropy increases (final entropy > initial).

Answer:

Dry ice (solid \( \text{CO}_2 \)) sublimes.
