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 elements move more slowly allowing the lovable forces betwixt them to become stronger. Eventually, these forces become strong affluent to require the molecules in a fixed position (they arse 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 adjoiningness to each other and the solid usually has a very ordered arrangement of molecules in what is known as a crystallization latt ice. Water is exceptional because it can increase the lovable forces between its molecules with an arrangement where each establish molecule is surrounded by only four other piddle molecules (If you think of a molecule as spherical - equivalent an orange - you willing realize that you could get as some(prenominal) as 12 molecules close to it if getting as close togeth er as possible was all that was required! - nevertheless a precise note. ;).

In many solids this close packing material is what happens - but pissing has an exceptionally strong type of attractive force between the molecules (known as hydrogen mystifying) 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 molecu les are forming a very open lattice structur! e, make the water to expand and form a block of ice.
