Question

A glass vessel is filled with water to the brim and a lid is fixed to it tightly. Then it is kept inside a freezer for hours. What is expected to happen?

• A. The water freezes to ice and the level of ice comes down
• B. The water in the glass vessel sink freezes to ice
• C. The glass vessel breaks due to expansion as water freezes to ice
• D. The water does not freeze at all

Answer 1

The correct option is C The glass vessel breaks due to expansion as water freezes to ice

When water converts to ice, its volume increases.

So inside freezer, water will convert to ice and will try to expand, which will break the glass vessel as its filled to the brink.
