Question

A plastic bottle completely filled with water when kept in freezer is likely to break give reason​

Answer 1

EXPLANATION: since water is an Incompressible fluid and due to density which makes freezing of water filled bottle starts cracking.Upon freezing,the density of ice decreases by about 9% that results in volume expansion.This increases causes enough force to break from rigid containers.This is the same force repeated on a daily basis,that create "potholes" in the roads of winter time.

The density of ice is 0.9167gm/cm^3,and the density of water is 0.9998gm/cm^3

Hope this will help you☺️

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 break.

Hope it helps!
