does warm air or cold air have more oxygen ?

Answer 1

If you mean air in general, both warm and cold have the same amount of oxygen. If you mean volumn of air, then cold will have more oxygen due to the density of the molecules being closer together. Warm air has less density of molecules. Thus, when you breathe in cool/cold weather, you are getting more oxygen into your lungs. Hot weather produces the feeling of "hard to breathe" due to the less amount of oxygen density.

Answer 2

There is more oxygen: colder air is denser, and a given volume would contain more oxygen. But that same dense, cold air also contains more nitrogen molecules and all the other components of air. So from that standpoint, the percentage of oxygen in the air doesn't change with temperature.

Answer 3

Cold

Answer 4

Both should have the same proportion of oxygen.
But given a fixed volume, there are more molecules in cold air, so there are more molecules of oxygen in cold air.

Answer 5

Well it would seem that cold air would. When one climbs to the top of Everest though you probably would'nt make it without oxygen tanks because of the altitude makes the oxygen thin even though it is very very cold.

Answer 6

Colder air is denser. The race car drivers love the cold race days! More O2 means more fuel, faster times!

Answer 7

cold air is far denser than warm air and therefore contains more oxygen

Answer 8

chilly air is denser than warmth air, so it incorporates no longer purely extra oxygen, yet to boot extra nitrogen, carbon dioxide, and different hint gases jointly with argon. the reason chilly air is denser is that the molecular action is way less lively, so the air has a lot less resistance to rigidity, inflicting it to contract right into a smaller volume.

Answer 9

cold...has more potential for oxygen also due to the increase in hydrogen

Answer 10

Hello cold .
