at cold enough temperatures gasses will seperate. but you will not see those temps unless your tank is on pluto

If we were to take a tank of air and let it sit for a long time... does the heavier gas (oxygen vs nitrogen) settle in the tank? Requiring the tank to be remixed?

Potential for Life
... Pluto's interior is warmer, however, and some think there could even be an ocean deep inside.
Some time ago, I saw an instructor roll a cylinder on the ground.
When I asked why the instructor was doing this, the instructor said that he checked quickly the gas contents and they got two very different readings when the measured it (apparently the first reading looked wrong so they read again immediately).
The instructor said that the gas wasn't probably mixed (this shop is doing partial fills), so he was trying to help it getting mixed.
This seemed a bit strange to me because I thought that with gases, as long as there would be some movement inside the cylinder, I thought that the gas would start mixing and stay that way (I am not good at physics so correct me if wrong).
Was the instructor correct or is it some kind of urban myth ?
That has been my experience as wellHelium does not preferentially "leak" past the valve seat or anywhere else for that matter.
The bailouts I filled with 9/72 three years ago are still full and still 9/72
The helium supply cylinder I bought 4 years ago is also still full

From a Google search...
Nitrogen gas has a molecular formula of N2 and a molecular weight of 28 g/mol. Thus, 1 mole of nitrogen gas weighs 28 g. Similarly, oxygen gas has a molecular formula of O2 and a molecular weightof 32 g/mol. ... This means that there is more oxygen than nitrogen in the same volume of gas.
those things have all sorts of issuesIt definitely leaks out of Lola manifolds.
They look cool thothose things have all sorts of issues
