Question

why does a glass bottle completely filled with water and tightly capped burst when placed in a freezer

Answer 1

Answer:

Given :

A glass bottle completely filled with water and tightly capped is kept in a deep freezer.

To explain:

Bursting of the glass bottle.

Concept:

Water follows anomalous expansion property. This property helps us to explain the fact that water undergoes expansion when freezed at Sub-Zero temperatures.

Explanation:

When water filled glass bottle is kept in a deep freezer, then water in the bottle expands in volume.

Such volume expansion results in pressure exertion on the bottle wall in a perpendicular manner.

When the pressure exceeds the critical limit of glass bottle, it cracks and bursts.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow}{Answer}}$

1. The temperature of air in the freezer (deepfreeze) compartment of a refrigerator is less than 0°C.

2. When a plastic bottle, completely filled with water, is kept in this compartment, the temperature of water falls below 4°C and the water expands.

3. Even when water freezes and ice is formed, there I an increase in the volume.

4. It exerts a large pressure on the sides of the bottle.

Hence, the glass bottle is likely to burst.

Hope it helps!
