Entropy: an Ice Cube at 0°C Is Placed in a Very

question 40

Multiple Choice

Entropy: An ice cube at 0°C is placed in a very large bathtub filled with water at 30°C and allowed to melt, causing no appreciable change in the temperature of the bath water. Which one of the following statements is true?

• A) The entropy gained by the ice cube is equal to the entropy lost by the water.
• B) The entropy lost by the ice cube is equal to the entropy gained by the water.
• C) The net entropy change of the system (ice plus water) is zero because no heat was added to the system.
• D) The entropy of the system (ice plus water) increases because the process is irreversible.
• E) The entropy of the water does not change because its temperature did not change.
