What will happen if a glass bottle is completely filled with water, sealed with a lid and put into a freezer?
Answer & explanation
Correct answer: option 1
The correct answer is option 1. Eventually, the ice will burst the glass bottle.
Here is a breakdown of why:
Water's Anomalous Expansion: Unlike most substances that contract when freezing, water expands when it turns to ice. This increase in volume is about 9%.
Closed System: With a completely filled and sealed bottle, the water has nowhere to go as it expands during freezing.
Pressure Build-up: The expanding ice creates significant pressure inside the bottle.
Breaking Point: Glass is weak in tension, meaning it can't withstand strong pulling forces. The built-up pressure from the expanding ice can exceed the tensile strength of the glass, causing the bottle to crack or shatter.
Therefore, it's not safe to freeze a completely filled glass bottle of water.
