On a warm summer day Mrs. George sliced some strawberries and placed them in a zippered sandwich bag and sealed it with enough air to provide protective air space for the strawberries. She then placed the sealed bag in the refrigerator to keep the strawberries cool. Describe what happens to the bag as it cools in the refrigerator. Why does this happen?
