Imagine that you fill a bucket to the top with water and then place the bucket outside in freezing weather. Which of the following describes what will happen when the water in the bucket freezes?

A. The level of the water and the bucket itself will not be changed by becoming frozen.

B. The level of the water will be lower once it is frozen and the molecules are more compact.

C. The sides of the bucket will be pushed out and the level of the water will be above the rim of the bucket.

D. The level of the water will be uneven once it is frozen because some of the water will remain as a liquid in the bucket.
