Question

A bottle filled with water cracks on freezing because the density of ice is less than water.

• A. True
• B. False

Answer 1

The correct option is A True

When water freezes, the ice formed expands and occupies more volume than the volume initially occupied by water. Hence, the same mass of water takes up more volume upon freezing and therefore has less density than water, i.e ice. This expansion causes the bottle of water to crack on freezing.
