Sagot :

Final answer:

When water changes to ice, its density decreases due to hydrogen bonds causing the molecules to be spaced farther apart, resulting in ice being less dense and able to float on liquid water.


Explanation:

When water changes to ice, its density decreases because water expands when it freezes due to hydrogen bonds, causing molecules to be spaced farther apart in ice. The volume of ice is about 9% greater than liquid water, making ice less dense and allowing it to float on liquid water.
