A majority of you reading this article can remember learning about the molecules that make up gas, liquids and solids. Maybe it was last year or maybe in a fun little children’s book, or maybe you are learning about this for the first time.
Basically, when you have water you have these atoms identified as H2O. That means you have one oxygen atom connected to two hydrogen atoms. This is a basic structure. Well, water, as a liquid, has weak hydrogen bonds between itself and the other atoms (one drop of water can contain 6X1023atoms). That means that the hydrogen atoms connected to the oxygen atoms are being attracted to each other. This creates the structure for a water molecule.
However, as the temperature of the water drops these atoms are attracted to each other with more intensity. So, as these atoms begin to come together they form a certain structure. It also creates a wide (if you can call such a miniscule width “wide”) area between the water molecules. Because of this the water becomes a solid, ice.
It is at this point that the ice begins to expand.
When the water molecules bond together (called a hydrogen bond) they form a structure that has a area between them that cannot be used as free space. So, when quadrillion and quadrillions of atoms are connecting you have a water structure that takes up more space then the jumbled together water . . . read rest of article >>>
