Co2 Escape

(1/2) > >>

monomer77:
How fast does CO2 escape from a container. Like if a bottle or keg is filled with CO2, will it immediately escape right out the hole when it's opened?

tom:
Good question. Gases diffuse to fill their space - that's part of the definition of a gas.
It depends on the opening and I'm sure there's all sorts of diffusion coefficients involved.
So it will diffuse out (and outside gases in), but not immediately.

oscarvan:
I would think that it is a function of pressure and the size of the hole....

monomer77:
Let's say it's a carboy filled up. Once the bung is pulled out, does the gas jump right out?

oscarvan:
OK, it's not pressurized...... No. CO2 is heavier than air and will "sit" in the carboy if not disturbed too much. If you put a hole in the bottom it will flow out.
