How is a juice box in the freezer a physical change?

When a juice box is placed in the freezer, the liquid inside undergoes a physical change as it cools down and eventually freezes into ice. This process involves a change in state from liquid to solid without altering the chemical composition of the juice. Once removed from the freezer, the ice can melt back into liquid juice, demonstrating that the change is reversible. Thus, the freezing of a juice box is a clear example of a physical change.
