    A water pipe freezes and cracks on a cold night

    Explanation:

    A water pipe freezing and cracking is a physical change, not a chemical change. A physical change is a change in what the item looks like, feels like, or how the item has a different form. The water pipe freezing is an example of a physical change because the liquid water has turned to frozen water. The frozen water has expanded the pipe, causing it to crack. There are no chemical changes taking place in this scenario.

    3). The pipe cracks.
