The structure of water is such that the molecules are held together by hydrogen bonding, and the geometry of the water molecule is a bent structure. This hydrogen bonding gets stronger as the temperature gets lower. Ice has a crystalline structure such that the atoms are organized in a simple repeating structure. The crystalline structure of ice is a repeating arrangement of eight molecules of water. Ice becomes less dense that liquid water, and that's why it floats. But by the same token, it expands to take up more space.

Why the surface of ice raises when it changes from water into ice?
water contracts when cooling until about 4 deg. C. From that temp. further cooling causes the water to expand. as it freezes it continues to expand, that is why ice floats.
When ice melts does it expand or contract?
When water turns from water into ice, it actually does expand. Depending on the salinity of the ice, it will however contract slightly (if fresh water) or it will expand slightly and then contract (as the temperature lowers). You'll notice that if your freezer is too cold, the ice cubes in the trays will actually have cracks in them, this is an example of the relief of internal pressure created by the contraction.
Does water continue to expand as it cools after forming ice?
No, water reaches its maximum density at about 4 degrees Celsius and starts to expand as it cools further. When water transitions into ice, it expands due to the crystal lattice structure of the ice molecules.
How much does the iceshelf in Antarctica expand?
The ice cap -- which includes the ice shelves -- doubles the size of the Antarctic continent in winter.
What will happen to a tied balloon that has dry ice inside it when it is placed in room temperature water?
The balloon should expand because the frozen carbon dioxide (dry ice) will sublime into carbon dioxide gas when placed into the room temperature water. The gas will expand, causing the balloon to expand.
Does water expand when turned to ice?
Yes. This increases its volume, which results in a decrease in its density.
Does Ice contract when cooled and expand when heated like most other solids?
yes
Does liquid expand when it becomes a solid?
Yes, it does. When water freezes, the liquid expands, thus causing the layer of ice to be thinner. This why ice floats.
Why does ice crack when put into water?
Ice cracks when put into water because the sudden change in temperature causes the ice to contract and expand rapidly, leading to stress on the ice structure and resulting in cracks forming.
Occurrence of the balloon when taken out of ice bath?
When a balloon that was inflated in an ice bath is taken out into a warmer environment, the air inside the balloon will warm up and expand. This expansion increases the pressure inside the balloon, causing it to expand and possibly burst if the pressure becomes too high. This is because gases expand when heated and contract when cooled.
Can you keep ice from expanding?
