Water has this unusual
behavior when cooled at <span>4 degrees Celsius; it expands slightly until
it reaches the freezing point and continue to expand by approximately 9%. This characteristic has something to do with the structure of the water molecule where there is a
strong tendency to form a network of hydrogen bonds and each hydrogen atom is
in a line between two oxygen atoms. These bonds force the crystalline
structure to be very open into hexagonal form and expand dramatically.
