Tried this test and it worked well, better than I thought, and basically because of the 'Law of conservation of mass' - no vapor leaked because the vapor pressure inside the Solo II remained almost the same through the 3 mintues of testing - and the taste was also good. actually pretty good.
"Vapor pressure" really means something different than you intend here? It's a temperature related expression of the tendency to evaporate (usually from liquid to gas, although there are rare solid to gas cases like dry ice and moth balls) at any given temperature. It's a pressure, usually in mm of Mercury, at which the material evaporates at the exact rate as it condenses. It's what makes fog work, and water boil since it's vapor pressure is 760mm ('normal pressure') at 100C. So water gas would make up 100% of the 'air' above the water? At lower temperatures the reduced pressure makes up a percent of the air, which backs into 'relative humidity'.
The total pressure remains the same. The THC vapor simply displaces Oxygen or Nitrogen molecules near by, and becomes a percentage of the total. It's not like steam escaping a boiling tea kettle.
Anyway, the fact that no vapor (which is really a small part of the total air/vapor mix we inhale) escapes is related. It condenses out on slightly cooler areas. That is it 'recycles' back to liquid again awaiting our pleasure. In the heyday of PD, many of us spaced out with a stem of herb (about .035 grams) warming in the unit.....
overnight. The vapor recycled, all night, and gave still potent (but not very tasty at all) hits the next day. Not advised, of course, but it demonstrates whey the good stuff doesn't 'get away' over reasonable times. While not advised, many of us conducted this experiment........
If you've ever watched the big boys 'doing dabs' you can see this in action. There the cloud over then hot nail is 'saturated', basically pure gas at that temperature, but as soon as it cools even a little bit that pressure has to drop so 'THC fog' forms. That fog is an aerosol technically (small clumps of molecules, distributed through the air), not really vapor (individual molecules) as we call it. It's not individual molecules but clumps from a micron (thousandth of a mm) or a bit less to several microns in size. This is why some vapes are more efficient than others it seems, given the same loads/concentrations. Particle size in the several microns never makes it deep into the lungs, rather gets trapped before. Very large ones never make it past your mouth and throat. Very tiny ones may go deep but statistically are unlikely to touch moist tissue and are simply exhaled to no net effect. As I understand it the 'ideal particle size' for us is in the few micron range. Some vapes produce more of these than others, percentage wise.
Or not.
And I think 'conservation of Mass' is really a religious term....having to do with Catholics I think?
Glad you got good results. That's what counts in the end. "A rose, by any other name" and all that.
Regards to all.

Used it all already. So I have been using my EQ with the balloons and ABV. Amazing how high you can get with recycled ABV. I use it at a higher temp, so I have to be careful of combusting it(yuck). So I really don't ever run out of weed.
