Question

Why does ice float on water?
Options
A Because ice is heavier
B Because water expands when cooled
C Because ice is warmer
D Because the hydrogen bonding in water causes water molecules in ice to align in an open lattice structure, making ice less dense than water
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The hydrogen bonding in water causes water molecules in ice to align in an open lattice structure. This means water expands as it freezes so ice is less dense than water.

Hint

The notes explain this unusual property of water.
