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.

∙ 14y agoi don't think it does. here's an experiment i did for my Climatology project:
take a glass bottle and put a balloon (with no holes) over the top. put it in the freezer for five minutes (or the freezer for 1 or 2, if u want it to go faster, just don't let it completely freeze; you're just trying to get the air inside it cold). take the bottle out and if the room that you put the balloon in was warm, the balloon will have kind of sucked in, because the air contracted. now, get your faucet as hot as it'll go and get it running, run it over the bottle for a minute or two and then you'll get results! the balloon on the bottle will start to inflate because the air expands!
so i don't think cold air takes up more space than warm, but i do know that ice takes up more space than water...

∙ 13y agoHot air has higher air pressure because cold air sinks
Wiki User
∙ 13y agoHot air because it spreads out as it becomes less dense. This makes more pressure than cold air does.
Wiki User
∙ 14y agoThe more hot air comes than cold air and the hot air takes more space

cold air, it's denser.

∙ 13y agoYes, warm air does take up more space.

What property of gas does air exhibit?
The property of air that a gas exhibits is that it can be compressed and it occupies space.
Which of the following has mass and takes up space?
Anything that lives except air, light, sound.
What happens when the air cools?
as air cools, the space it occupies becomes less. this result in an increas density
Does air have mass and take up space?
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
What term is defined as anything that occupies space and has mass?
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.
How can you prove air is matter?
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.
How does air occupies space?
air,like all matter occupie space
Does air have matter?
Air is a matter because it occupies space.
Does cold air or warm air have more molecules occupying a cubic centimeter of space?
cold air
Does all matters fills space?
Not all occupies space, because air does not take space.
Cold air has more molecules occupying a cubic centimeter of space then warm air therefore it has a what pressure?
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
What property of gas does air exhibit?
The property of air that a gas exhibits is that it can be compressed and it occupies space.
What does air occupy?
Like all other forms of matter, air exists in space and time. It occupies the space-time continuum.
Which of the following has mass and takes up space?
Anything that lives except air, light, sound.
Air is matter or not?
air is matter because the definition of matter is "any thing that occupies some space and mass ".air occupies some space and mass. it occupies container volume. air occupies the space and air also have some mass so it is matter
What happens to air as it cools?
As air cools, the space it occupies becomes less. This results in an increase in density.
What happens when the air cools?
as air cools, the space it occupies becomes less. this result in an increas density
