Final answer:

Water expands when freezing, leading to crystalline structures forming and exerting pressure on container walls such as plastic bottles.


Explanation:

Part 1: When water freezes, it expands by approximately 9%. This expansion is due to the formation of crystalline structures in the water as it transitions to a solid state.

Part 2: A plastic bottle filled with water bursts when the water freezes because as it expands, it exerts significant pressure on the walls of the bottle. The rigid plastic is unable to withstand this pressure, causing the bottle to deform or burst.
