Why does water expand when it is frozen?

Water behaves differently than almost all other fluids because it runs when it is frozen. As a liquid is cooled down the motes move more behind allowing the lovable forces betwixt them to become stronger. Eventually, these forces become strong abundant to require the molecules in a fixed position (they hindquarters relieve vibrate but not change their relational positions) and the liquid becomes a solid. The molecules in the solid have r severallyed an optimum keep mumness to each other and the solid usually has a very ordered arrangement of molecules in what is known as a crystallization latt glassful. Water is exceptional because it can increase the magnetic forces between its molecules with an arrangement where each get molecule is surrounded by only four other piddle molecules (If you think of a molecule as spherical - handle an orange - you willing realize that you could get as umpteen as 12 molecules approximately it if getting as close together as po ssible was all that was required! - yet a precise note. ;).

In many solids this close backpacking is what happens - but water has an exceptionally strong type of fondness between the molecules (known as hydrogen marrying) and each hydrogen bond is at least 10 times stronger than the other types of attractive forces that hold molecules together. The uttermost number of hydrogen bonds a water molecule can form is 4 and in ice each water molecule is doing just that. Water expands to around 9-10% its original volume. So the attractive forces are maximized even though the molecules are forming a very open lattic e structure, causing the water to expand and! form a block of ice.
