Question:

What will happen if a glass bottle is completely filled with water, sealed with a lid and put into a freezer?

Options:

Eventually, the ice will burst the glass bottle

Weight of the glass bottle will increase after water freezes into ice

Nothing will happen

The glass bottle will be deformed due to atmospheric pressure on the bottle after the water freezes

Correct Answer:

Eventually, the ice will burst the glass bottle

Explanation:

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.
