Final answer:
Hydrogen bonds in water create unique properties like lower ice density, important for life processes.
Explanation:
Hydrogen bonds are formed in water due to the attraction between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule. In the liquid state, these hydrogen bonds constantly break and reform as the water molecules move. When water freezes to ice, the hydrogen bonds form a rigid network, creating a less dense structure than liquid water.
When water is boiled, the increased kinetic energy causes the complete breaking of hydrogen bonds, allowing water molecules to escape as gas. This unique behavior of water, due to hydrogen bonding, is vital for life processes and contributes to its various physical properties.
Ice, despite being a solid, has lower density than liquid water due to the specific arrangement of water molecules held together by hydrogen bonds, resulting in its ability to float on water.
