why do ice floats on water?

Asked by Riya Rose | 25th Oct, 2013, 12:06: PM

Expert Answer:

  • 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.
