full

/fo͝ol/

adjective

  1. containing or holding as much or as many as possible; having no empty space.

A glass holding air could contain more if the air were pressurized, therefore it is not full.

The same thing applies to water or any other material you fill it with.

Then 'technically' no glass in the world has ever been full.

Never say never but yeah that’s the point if you really wanna be that picky

I’d say a glass is full when it overflows upon adding more fluid

Is it though? It's denser at extreme depth. I'm trying to get my tired brain around this and failing.

Fill your cars combustion chambers up with water and tell me if it compresses lol

Of course not because the conrods will bend first. But as an awake person I can now remember that water is indeed denser at great depth (to an extent that is reflectee in the anatomy of the fish that live there). So it is compressible it's just not easy.

Touché my friend!

However... Having no empty space", you yourself posted as being full too?

But agree to an extent as well with your argument. Which would also mean that they're never full because most things can be compressed under extreme pressure. For example in a black hole...

That's the thing about semantic arguments; no one is ever right because definitions aren't rigorous. Words mean only what they are understood to mean, and a glass full of air is understood to be empty.

When you breathe in, are your lungs full?

254LEX t1_ja3pd81 wrote

Yes, because lungs are meant to hold 1 atm air. Glasses are meant to hold liquid.

You can put anything you want in glasses. Pens, food, toenail clippings

It’s it’s in an unpressurized environment it will be impossible to hold more, therefore even if it’s an unpressurized environment under that definition it would still be full.

254LEX t1_ja5oi5j wrote

If the air were colder, it would also be more dense and therefore more would fit in the glass. But this whole discussion is pointless. It's a semantic argument, and saying that things are always (or never) full makes the word 'full' meaningless. Neither argument aligns with how the word is used, therefore they are both wrong.

tillytubeworm t1_ja7rad6 wrote

If the air were colder it’d be a differently pressurized environment, so within any specific environment it’d always have the potentiality to be full. So even with your semantics I think OP’s showerthought is accurate in that sense. But not in the sense of using vacuum suction to remove the air.
