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 scraps move more slowly allowing the lovable forces betwixt them to become stronger. Eventually, these forces become strong bountiful to require the molecules in a fixed position (they hobo relieve vibrate but not change their relational positions) and the liquid becomes a solid. The molecules in the solid have r severallyed an optimum finishness to each other and the solid usually has a very ordered arrangement of molecules in what is known as a crystallization latt trumpery. Water is exceptional because it can maximise the lovable forces between its molecules with an arrangement where each build molecule is surrounded by only four other piddle molecules (If you think of a molecule as spherical - like an orange - you willing realize that you could get as galore(postnominal) as 12 molecules somewhat it if getting as close together as poss ible was all that was required! - equitable a precise note. ;).

In many solids this close pugilism is what happens - but water system has an exceptionally strong type of magnet between the molecules (known as hydrogen clinging) 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 l attice structure, create the water to expan! d and form a block of ice.
