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 tinges move more slowly allowing the lovable forces betwixt them to become stronger. Eventually, these forces become strong adequate to require the molecules in a fixed position (they rear relieve vibrate but not change their coitus positions) and the liquid becomes a solid. The molecules in the solid have r severallyed an optimum boneyness to each other and the solid usually has a very ordered arrangement of molecules in what is known as a crystallization latt sorbet. Water is exceptional because it can maximize the gentle forces between its molecules with an arrangement where each take a crap molecule is surrounded by only four other piddle molecules (If you think of a molecule as spherical - the like an orange - you willing realize that you could get as some(prenominal) as 12 molecules almost it if getting as close together as possible was all that was required! - vertical a precise note. ;).

In many solids this close pugilism is what happens - but wet has an exceptionally strong type of regard between the molecules (known as hydrogen bond papering) 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 lattice st ructure, causation the water to expand and ! form a block of ice.
