Do air inflated items that are pressurized, float better, the same, or worse than items--->?
Answer:
Floating is a matter of buoyancy and has little to do with air pressure other than making the object holding the air buoyant.
Which is more buoyant...a Styrofoam football or a leather football with air? with no air? Adding more air sometimes although not always increases the buoyancy and therefore it floats. But the Styrofoam floats without adding anything to it.
The answer to your question is it depends on the amount of weight you have on the inflated object. A inflated rubber boat with very little air pressure will not hold as much weight and will submerge easier than a full to capacity boat.
I'll say "yes"
it seems to reason because it's more 'stuff' that's trying to not be submerged
it's like comparing a floating twig to a floating tree trunk in terms of the amount of trapped air
they both float but i'd rather hold onto the tree trunk LOL
I am an anesthesiologist as well as a former scuba diver, and I can tell you that, without a doubt, a tank that is filled with a gas under pressure weighs more than a tank filled with gas at atmospheric pressure. Anyone who has lifted a propane tank from a gas grill also knows this. So, theoretically, at least for a rigid device that is inflated, the lower the pressure, the better it should float. I don't know my physics well enough to know if this would necessarily apply to a collapsible inflatable, because other factors could be at play.
It would float worse since there's more mass per displacement.
If you had a perfectly rigid body, the best way to make it bouyant would be to create a vacumn inside this body.
*ITS VERY SIMPLE*
pressure means higher density ,
higher density means more weight in the same volume (space) ,
more weight in the same volume means it floats worse
