Question

a glass bottle completely filled with water and tightly closed at room temperature , is likely to burst when kept in the freezer of a refrigerator.

Answer 1

HEY DEAR ...

It is due to anomalous expansion or strange behavior of water.
The expansion of water takes place as it is cooled from 4 degrees Celsius to zero degree Celsius. This behavior is unusual because most substances contract when they are cooled. But water expand on solidifying. Due to this expansion a glass bottle completely filled with water and tightly closed at room temperature is likely to burst when it is kept in fridge.

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 bottle is likely to burst.
