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.
air molecules are more spread out and have lower mass compared to water molecules. This leads to a lower density of air compared to water at the same temperature and pressure.

What are 5 examples of floating and sinking?
Ice floats in water because it is less dense than water. A wooden boat floats on water because it is less dense than water. A balloon filled with helium gas floats in the air because it is less dense than the surrounding air. A cork floating in water floats because it is less dense than water. A rock sinks in water because it is more dense than water.
Is liquid water less dense then Ice?
Yes, liquid water is less dense than ice. When water freezes, its molecules form a crystalline structure that spaces them out, causing ice to be less dense than liquid water. This is why ice floats on water.
Why does an eraser float?
An eraser floats because it is less dense than water. The air trapped inside the eraser adds buoyancy, allowing it to float on the surface of the water.
What would happen if an object was less dense than water?
If an object is less dense than water, it would float on the surface of the water. This is because objects less dense than water displace an amount of water equal to their weight when they are immersed, resulting in buoyancy force that keeps them afloat.
Why is air more buoyant than water?
Air is more buoyant than water because it has a lower density. The density of an object determines its buoyancy - objects with lower density than the fluid they are in will float. Air is less dense than water, so objects are more likely to float in air than in water.
Does ice float because it is less dense than water?
Yes. Anything that is less dense than water will float on water.
Icecubes float in water because they are less?
Dense
Does lithium sink under water?
No, lithium is less dense than water, so it will float on the surface of water.
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.
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.
Is a rubber ducky more dense then water?
No, a rubber duck is less dense than water. It will float on the surface of the water because it is less dense.
What are 5 examples of floating and sinking?
Ice floats in water because it is less dense than water. A wooden boat floats on water because it is less dense than water. A balloon filled with helium gas floats in the air because it is less dense than the surrounding air. A cork floating in water floats because it is less dense than water. A rock sinks in water because it is more dense than water.
Is oil less dense then water?
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Is water less or more dense than water?
Ice is less dense than water
Ice is less dense than water because of which type of bond?
Ice is less dense than water due to hydrogen bonding. When water molecules freeze into ice, the hydrogen bonds hold the molecules in a more spaced-out, lattice-like structure, causing ice to be less dense than liquid water.
Bubbles rise in water because they a. are so tiny b. less dense than water c. more dense than water d. fluids?
Bubbles rise in water because they are less dense than water. The buoyant force pushes the lighter bubble upwards through the denser water.
Why can a candle float on water?
Because wax is less dense than water.
