Ice is less dense than water. Less dense floats, more dense sinks. When water freezes, its volume expands (more space between molecules), which means its density decreases so it floats.*
* Among compounds, this property is unique. Among elements, it is less rare. It is shared by: Si, Ga, Ge, Bi, and Sb.

Why does ice float on water but sinks in methylated spirits?
The density of rubbing alcohol is 75% that of water. Thus ice (frozen water which is roughly equal in density to liquid water), sinks in rubbing alcohol since it has more mass per cubic millimeter than the alcohol does. In order to float, the object would have to be less dense than the alcohol per cubic space.
When ice melts does it get heavier or lighter?
No. As it melts, it will saturate the layer below it, so that layer of snow will be heavier but there will be the same amount of water-equivalent on the limbs. And some of the water will likely drip off the branches anyway. In other words, the most weight that will be on tree limbs is right after the snow stops falling.
What is the density of ice compared to that of water?
Because ice is lighter than water in liquid state. Curiously, water is the only non-metallic substance on Earth whose density in solid form is less than its density in liquid form. From Wikipedia: Liquid water is most dense, essentially 1000 kg/m3, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the temperature drops to 0 °C. This is due to hydrogen bonds forming between the water molecules, which line up molecules less efficiently (in terms of volume) when water is frozen.
In which liquids will an ice cube float?
in water or anything which is denser than ice
What unusual fact about ice causes it to float in water?
Ice has a lower density than water.
Ice is heavier than water or not?
Ice is lighter (less dense) than water. Which is why ice can float on the surface of water.
If cold water sinks why is ice on top of pond?
Ice is lighter than the water it displaces .
Why is ice lighter than liquid water?
ice is boring and water is fun. bla-bla.
Why ice berg is over the water?
The iceberg is lighter than water, but not by much. The ice floats, but about 80% of the iceberg is under water.
What is the benefit of floating ice?
The question is meaningless. Ice floats on water because it is lighter than water that how it is there is no advantage or disadvantage.
What are facts about ice cubes?
Ice cubes will melt faster in darker colour water than lighter colour water
Why does ice cubes float in your drink but crushed ice sinks and blocks your straw?
Because ice is lighter than water
Lighter than what you are made of More of you is hidden Than is seen?
An Iceberg Made of water but ice is lighter than water. Nine tenths of an iceberg is below the surface and so it is unseen.
Is ice heavier than water?
Ice is lighter than water. That is why it floats on water.The term "lighter" is confusing here. A pound of water will still freeze into a pound of ice. However, the the pound of ice is less dense than the pound of water, so it floats. This gives the impression that a pound of ice is lighter than a pound of water. Well really, it depends on the quantity of both ice and water. However lets say if you had 1 kilogram of ice and 1 kilogram of water. The ice would weigh more because the particles are pulled together more and they're no longer liquid (physically) and the ice would be bigger and heavier (obviously) .
Why ice is denser than water?
ice has tetrahedral structure due the which there are left some empty spaces beetween it & it is lighter
What weights more frozen water or normal?
Ice has a lower density than water (hence it floats on it) and as such will be lighter than the same volume of water.
What does densety have to do with an ice cube floating?
Because the density of ice is less than that of water, the ice floats on the water. Think of density as weight. In cheer leading the heavier people pick up the lighter people because it is easier. It is easier for the water to "pick up" the ice because the ice is lighter. Therefore, the ice floats on top of the water instead of sinking to the bottom
