Freezing Forms

ICE DEMYSTIFIED

Water is very odd when in comes to its freezing pont. Water's solid form is less dense than its liquid form,

but for alot of other substances the most dense is it's solid form and not it's liquid. Another interesting thing

about ice is that it floats on water. Well, between water molocules there are weak bonds called hydrogen bonds.

(Hydrogen bonds and floating ice will be explained in the lower information and the other link to this page.)

WHY DOES ICE FLOAT?

What other observations or facts are known?

Because ice floats, we can infer that ice must be less dense than water.
If water is frozen in a glass jar, the glass jar breaks because the ice expands

Conclusion: The volume of ice must be greater than the same mass of liquid water.

Like most things that float, ice floats because it is less dense than liquid water. Ice is about 9% less dense.
When ice forms, it takes up about 9% more space than it did as a liquid.
