Liquids generally have lower density as compared to solids. But you must have observed that ice floats on water. Find out why?

Hint: Water has more hydrogen bonding in a given area than ice and ice has more intermolecular space than water.
Explanation of answer:In liquid form, water has strong hydrogen bonding between molecules but when water freezes into ice, the hydrogen bonds that form allow the molecules to be spaced further apart by locking them into fixed positions, hence making them take more space.That is why overall density decreases and making ice float on the water.
