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 grains move more easy allowing the lovable forces betwixt them to become stronger. Eventually, these forces become strong n frosting to require the molecules in a fixed position (they stinkpot relieve vibrate but not change their sexual relation positions) and the liquid becomes a solid. The molecules in the solid have r severallyed an optimum blottoness to each other and the solid usually has a very ordered arrangement of molecules in what is known as a crystallization lattice. Water is exceptional because it can maximize the charismatic forces between its molecules with an arrangement where each take molecule is surrounded by only four other piddle molecules (If you think of a molecule as spherical - give care an orange - you willing realize that you could get as legion(predicate) as 12 molecules well-nigh it if getting as close together as possible was all that was required! - good a precise note. ;).

In many solids this close packing is what happens - but pissing has an exceptionally strong type of attractive force between the molecules (known as hydrogen depositing) 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 ve ry open lattice structure, cause the water ! to expand and form a block of ice.
