Why does pineapple juice expand when frozen?

PineApple Juice expands when frozen due to the presence of water, which constitutes a significant portion of the juice. When water freezes, its molecules arrange themselves into a crystalline structure that takes up more space than in its liquid form, leading to an increase in volume. Additionally, the sugars and other components in the juice can also contribute to the expansion process. As a result, if pineApple juice is frozen in a sealed container, it can cause the container to crack or burst due to the increased pressure from the expanding liquid.
