The density of air varies with temperature, so for a given pressure and volume cold air will weigh more. With more weight comes more oxygen(and more of everything else too), all other things being equal.
The property of air that a gas exhibits is that it can be compressed and it occupies space.
Anything that lives except air, light, sound.
as air cools, the space it occupies becomes less. this result in an increas density
we can say that air has mass and it occupies space by a small activity: take an inflated balloon and if we press it we can see that it is difficult to press becuse it hs mass and occupies the space avialable
Anything with mass and space-holding properties is considered to be matter. Atoms make up the basis of all matter. Air has mass and takes up space.
air,like all matter occupie space
Air is a matter because it occupies space.
Like all other forms of matter, air exists in space and time. It occupies the space-time continuum.
cold air
The classical definition says anything that occupies space is matter. To prove air occupies space we can do a small experiment. Take a balloon and blow air in it. The balloon expands and this proves that air occupies space. And thus we can prove air is matter.
Not all occupies space, because air does not take space.
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
The property of air that a gas exhibits is that it can be compressed and it occupies space.

as air cools, the space it occupies becomes less. this result in an increas density
As air cools, the space it occupies becomes less. This results in an increase in density.
Yes, air has weight due to the force of gravity acting on it. Additionally, air occupies space as it fills the atmosphere surrounding Earth.
