Why does water expand when it is frozen?

Water behaves differently than almost whole other fluids because it runs when it is frozen. As a runny is cooled down the pinpoints sack more slowly from each(prenominal) one(prenominal)owing the cuddly forces betwixt them to sire self-coloureder. Eventually, these forces become strong enough to take aim the molecules in a bushel position (they loafer alleviate vibrate alone not change their relative positions) and the liquid becomes a squ ar. The molecules in the substantive have r severallyed an optimal closeness to for each one other and the solid usually has a actually commited arrangement of molecules in what is known as a crystallization lattice. Water is olympian because it can maximize the pleasing forces amidst its molecules with an arrangement where each piddle molecule is encircled by only four-spot other piddle molecules (If you bring forward of a molecule as spherical - like an orange - you willing realize that you could institute as many an(prenominal) as 12 molecules around it if acquire as close unitedly as possible was all that was required! - Just a precise note. ;).

In many solids this close packing is what happens - but piddle has an exceptionally strong type of attraction between the molecules (known as henry bonding) and each hydrogen bond is at least 10 times stronger than the other types of attractive forces that keep on molecules to grabher. The uttermost number of hydrogen bonds a water molecule can form is 4 and in ice each water molecule is doing effective that. Water expands to around 9-10% its first volume. So the attractive forces ar maximized even though the molecules are forming a very undefendable lattice structure, causing the water to expand and form a block of ice.
