A plastic bottle, completely filled with water, when kept in a freezer, is likely to break. Give reason

Text Solution

Verified by Experts

(1) The temperature of air in the freezer (deep freeze) 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. Even when water freezes and ice is formed, there is an increase in the volume. It exerts a large pressure on the sides of the bottle and hence the bottle is likely to break.
