Due to hydrogen bonds, the density of water decreases as it freezes (decrease starts at 4oC). To see a full explanation of why ice floats in water, see the related question below.
Continents float high because they are less dense than the underlying mantle layer of the Earth's crust. This buoyancy allows them to "float" on top of the denser mantle, similar to how ice floats on water.
Ice will float in ethanol because ice is less dense than ethanol. The density of ice is about 0.92 g/cm3, while the density of ethanol is about 0.79 g/cm3. This difference in density causes ice to float in ethanol.
in water or anything which is denser than ice
Ice floats on sea water because it is less dense than water. When water freezes, it forms a crystalline structure that spaces the water molecules farther apart, causing ice to be less dense than liquid water. This density difference allows ice to float on top of the denser sea water.
Tectonic plates and ice cubes in a bowl of punch are both floating on a less dense material. Just like how ice cubes in punch float on the liquid because they are less dense than the liquid, tectonic plates "float" on the semi-fluid asthenosphere beneath them due to their lower density compared to the underlying mantle. This floating behavior allows both ice cubes and tectonic plates to move and shift around.
density
The property of ice that allows it to float in water is the ice's low density. When water freezes into ice, the molecules arrange themselves in a way that makes the ice less dense than the liquid water, causing it to float.
Buoyancy; negative density.
The low density of ice is what allows it to float on water. When water freezes into ice, its molecules arrange themselves into a more spaced-out, crystalline structure, making ice less dense than liquid water. This difference in density causes ice to float on water.
Ice is less dense than water, therefore, it is able to float on top of water, which is more dense than ice. Because of this unique property of water, life is able to exist in Antarctica, seeing that organisms would need to be able to utilize water for metabolic functions.

Ice floats on water because it is less dense than liquid water. When water freezes, it forms a crystalline structure in which molecules are more spread out, making ice less dense and causing it to float.
The property of water that allows things to float is buoyancy. Water exerts an upward force on objects placed in it, which counteracts the force of gravity pulling the objects down. This buoyant force is what allows objects to float in water.
The property of water that causes ice to float is its density. When water freezes into ice, the molecules form a crystal structure that spaces them apart slightly, making ice less dense than liquid water. This lower density causes ice to float on the surface of water.
Compared to water, ice has a lower density, which allows it to float. This is because the molecules in ice are arranged in a way that creates open spaces, making it less dense than liquid water.

An ice cube will not float in air because air has a lower density than ice, making it less buoyant. Ice is less dense than water, which allows it to float in water due to buoyancy. In air, the buoyant force is not strong enough to support the weight of the ice cube, so it will not float.
