When ice cubes are made, the entropy of water A. Does not change B. Decreases C. Increases D. May either increase or decrease depending on the process used

The correct answer is B. Decreases.

Entropy is a measure of the disorder or randomness of a system. When water freezes, it changes from a liquid to a solid. This change of state is accompanied by a decrease in entropy. This is because the molecules in a solid are arranged in a more ordered structure than the molecules in a liquid.

The following are the explanations for each option:

• Option A: The entropy of water does not change when ice cubes are made. This is not correct because the entropy of water decreases when it freezes.
• Option B: The entropy of water decreases when ice cubes are made. This is the correct answer.
• Option C: The entropy of water increases when ice cubes are made. This is not correct because the entropy of water decreases when it freezes.
• Option D: The entropy of water may either increase or decrease depending on the process used. This is not correct because the entropy of water always decreases when it freezes.
