At what sort of pressure?
1 atmosphere, so sea level pressure, per Diána Ürge-Vorsatz
I feel like a ton of C02 at air pressure should be bigger.
I know it's correct, but it looks like the amount of exhaust produced by a car idling for a few minutes, at a visceral level you just expect a literal tonne of gas to take up more volume.I assume CO2 is only a portion of the exhaust. Not sure if that’s what you were meaning already?
Edit: No idea of the quality of this source, but:
So what's coming out of a car exhaust is 13 per cent CO2, 13 per cent water (26 per cent sub-total) and 73 per cent nitrogen gas. The air that you're breathing right now is 78 per cent nitrogen gas, 21 per cent oxygen, and one percent everything else.
At what temperature?
Whatever it was about on Jan 27, 2024 in Vienna in the evening during the Science Ball. Probably about 10°C
But at what pressure?
~1 atm/bar.
-270°C
1 atm.
