Yes, liquid water expands as it freezes into ice, and therefore is lighter than water. That is why iceburgs float.

Ice has less density than Water. This is bizarre, because usually solid sinks in the liquid of the same material. However, due to water's polarity, water gets greater volume when it freezes. Density is mass divided by volume. So when the same amount of water gets greater volume by being frozen, ice acquires less density, and thus ice floats on the water. It is the same thing, when you freeze a glass bottle of coke full of water and close its cap, the volume of water expands as it freezes and it breaks the glass bottle.

If ice didn't float (meaning less dense than liquid water), none of us would be here...
The origins of life on earth would have been frozen out if frozen water sank to the bottom of lakes and oceans....
Think about it... How do fish survive in the Great Lakes???? Because the water BELOW THE ICE CAP never gets cold enough to freeze....
Because of the "kink" in the molecular bond forced by the pair of non-bonding electrons that oxygen has in H20... frozen water takes up more space than liquid water and thus is less dense...
density being mass/volume.... more volume at the same weight means lower density, thus ice floats on water...

yes ofcourse, because ice is less dense than water (even though ice being a solid and water being the corresponding liquid) due to the hydrogen bonded lattice in the structure of ice.

Yes; Ice has lower density than water

Of course. Plop an ice cube into a glass of water and see what happens.

Depends on what kind of ice.
In chemistry, the word "ice" can be used for any liquid that has been frozen. If you take molten iron and cool it down, you have iron "ice".

usually only 10% of it floats

if it's salt water. or if there is air trapped in the ice.

Yes, a very thin flat piece.
