Question

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

Answer 1

water expands when it gets cooler. There is no room in the bottle to store the expanded water.Due to this, the water applies pressure on the container causing it to burst.

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!
