Air is less dense because the particles are mainly of lower molecular mass with similar volume, thus having an inherently lower density, and also because air is free to expand (as it is a gas) where water is liquid and so cannot expand or contract to any major degree.

Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Is liquid water less dense then Ice?
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
Why does an eraser float?
Because it's less dense than water.
Why some materials sinks in water while others do not?
Some materials sink in water because they are more dense than the water. Others float because they are less dense than water.
Why does oil float on the surface of water?
Because oil is less dense than water.
Does ice float because it is less dense than water?
Yes. Anything that is less dense than water will float on water.
Ice is less dense than water because of which type of bond?
Ice is less dense than liquid water because of hydrogen bonds.
Icecubes float in water because they are less?
Dense
Why is water at 0 less dense than water at 4?
Water at 0 is less dense than water at 4 because at the 0 the volume is larger than at 4.
Does ice float because water becomes more or less dense when its frozen?
The structure of frozen water (ice) is less dense than the random arrangement of the water molecules in liquid water, thus ice floats because water becomes less dense when it is frozen. Because of buoyancy forces, an object placed in a liquid will float if it is less dense than the liquid and sink if it is more dense.
Is water less or more dense than water?
Ice is less dense than water
Where cool dense water sinks does it become more dense?
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Will crude oil float on water or sink?
Most (but not all) oil is less dense than water. That oil which is less dense than water will float. That oil which is denser than water will sink.
Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Why can a candle float on water?
Because wax is less dense than water.
Does lithium sink under water?
No, because it is less dense than water.
Why does a cork float on water?
because cork is less dense than water
