- In case of solid ice, the hydrogen bonding gives rise to a cage like structure of water molecules.
- Each water molecule is linked tetrahedrally to four water molecules.
- When ice melts, the cage like structure collapses and the molecules come closer to each other.
- Thus, for the same mass of water, volumes decreases and hence density increases.
- Therefore, ice has lower density than water at 273 K and that is why ice floats on water.
