Ok stupid question I know but I'm probably just thinking about it all wrong. If I have a container that can't be compressed in any way filled with air and I bring it to the bottom of the sea why would the air pressure inside increase? The way I'm thinking is that it is separated from any...

Hi all. Just got a question to ask, I'm slightly puzzled by it. Q. Say that you have a sealed container and you put in it 50% helium and 50% argon and you leave it for a few days. Because argon is heavier than helium, would the most of the helium rise to the top part of the container...

I have an interesting question, that I've been struggling with for a while now, but I'm somehow messing it up. I haven't found anything on the internet (hard to search for something like this) so I'm wondering if any of you know something useful about it, or do better at finding the solution...

Hi, I'm building a lens and stupidly rinsed one component before putting the lens body together with epoxy glue. Now when I leave the lens in the sun the trace of water left in the vacuumed lens body turns into condensation and blurs out the vision. I've seen loads of forums suggesting using...

If a gas will expand to fill the available space (container) does this still hold true if the "container" is the atmosphere? Assuming the gas(es) can escape (either in molecular or in subs - atoms) from the area around the Earth containing our atmosphere this means that the gas is not...
