Ice floating on water may seem ordinary, but it is actually a fascinating scientific phenomenon. The reason lies in the unique molecular structure of water and the effect of hydrogen bonding between its molecules. ❄️💧

Water molecules are made up of two hydrogen atoms and one oxygen atom, forming the well-known H₂O structure. These molecules are attracted to each other through hydrogen bonds. In liquid water, these bonds are constantly breaking and reforming as the molecules move freely. This movement allows the molecules to pack closer together. This close arrangement makes liquid water denser. 🔬

When water cools to 0°C and begins to freeze, the behavior of the molecules changes. Their speed slows down and the hydrogen bonds become more stable. Instead of moving freely, the molecules arrange themselves in a stable crystalline structure. This structure creates a repeating hexagonal pattern. ❄️

The important information is that in this crystalline lattice, there is more free space between the molecules than in liquid water. In other words, the molecules are spaced apart from each other. Although the mass of water remains the same, its volume increases when it turns into ice. Density decreases when density is divided by mass, so the increased volume reduces the density. 📉

Since ice is less dense than liquid water, it floats on the surface instead of sinking. This property has an important impact on nature. When lakes or ponds freeze in the winter, ice forms on the surface while the water below remains liquid. The layer of ice acts as an insulating blanket, helping aquatic organisms survive in cold environments. 🐟🌍
