Air is a mixture of different gases but the most notible of these are Nitrogen, Oxygen and Carbon Dioxide.
All the gases in air are significantly less dense than water.
The lower density is caused by their particles having great kinetic energy and therefore moving faster and further apart.
The effect of this is to have less particles per unit area which, therefore, means that each unit area will have significantly less mass than the same unit area of water.
Things with lower density will float on top of things with higher density.

Will the density of air float of sink?
The density of air is 1,225 g/L at STP.
Will scoria float or sink in water?
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
What makes an item to float or sink in water?
This depends on the density of this item: more denser than water-sink, less denser than water-float.
Does octane sink or float in water?
Octane is less dense than water, so it will float on the surface of water.
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
How do you make a plastic bottle submarine float then sink and float?
put water in to let it sink... then put air into it to let it float...
Does helium float or sink in water?
Helium gas is less dense than air, so it will rise and float in both air and water.
Do diamonds float on water?
No they sink to the bottom because they hold no air.
Why does the same piece of foil float or sink?
The same piece of foil can float or sink depending on its shape and how it is positioned in the water. If the foil is shaped to trap air, it will float. If the foil is crumpled or folded so it doesn't trap air, it will sink.
Why does a submarine can sink and float in water?
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
Does styrofoam sink in air or float?
sink
Would a crayon sink or float?
A crayon will generally sink in water because its density is greater than that of water. However, if the crayon has air pockets trapped inside, it may float due to the buoyancy provided by the air.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
Do clothes float or sink?
it will float as long as it is not fully covered water.
Why do apples float in water and pears sink?
Apples float in water because they have air pockets in their flesh, making them less dense than water. Pears sink because they have a denser flesh and fewer air pockets, causing them to be heavier than water.
Does asphalt sink or float in water?
Asphalt will typically sink in water because it is denser than water. However, if the asphalt is porous or has air trapped inside, it may have some buoyancy and float for a short period of time.
Will arsenic float or sink in pure water?
Arsenic is denser than water, so it will sink in pure water.
