Does the temperature of air at sea level have any bearing on the oxygen carrying properties of it?Cold air=less pressure psi according to my tire gauge.Less pressure=less oxygen per breath?Doesn’t sound right.
Football players skills seem to hold up in frigid conditions,or is this just a matter of all players having a lower performance speed?
Well, if you ask the Mount Everest climbers if there is less oxygen when there is less air pressure, you can be sure they’d say yes.
It seems to me that the same would be true at sea level with a low pressure area vs a high pressure area.
At low pressure there would be fewer oxygen molecules per breath. But probably not enough to notice, even at high exertion levels (like a marathon runner for example).
Cold air is more dense (takes up less space with the same number of molecules). So… cold air would give you less tire pressure (you have the same amount of air in the tire, but now it takes up less space), but MORE oxygen per breath (assuming you inhale a liter of air regardless of temperature, you will take in more molecules of (dense) cold air than if the air were warm).
This effect will be minimized by your body warming the cold air as it travels to your lungs. The warmed air will expand (become less dense). Your lungs like its air to be a pretty constant temperature, and your body is designed to provide air at that temperature by warming cold air, or cooling warm air.
I see that D_Frag did a much better job of reading the OP than I did. Sorry about that. I got hung up on the pressure aspect rather than the temperature aspect.
Carry on…
Oxygen is slightly denser than “air” . Mol Wt of Oxygen is aroind. 32 and that of Nitogen is areound 28.
