Answer:

because of the water filled in a bottle fully filled in a bottle and didnt having that much space so due to high temperature of the frezer it brokes

Answer 2

The reason for the bottle to break was the 'anamolous property of water'. Maybe, I am writing the word's spelling wrong. Search it on internet.

"Anamolous property of water" states that water expands when it reaches the temperature of 4° C or below while cooling. When the water reached 4° C, it started to expand and it did not get enough space to expand, so the bottle broke.

Way to avoid the breakage of bottle- Leave a little space filled with air in the bottle, or, in easy language, do not fill the bottle to the top. Leave around 2-3 cm depth empty from the surface of water in the bottle. If the water expands, it will occupy that empty space and the bottle will not contract.

Note- Cast iron also shows similar property.
