In the above air tight box there is a pressured gas.


When  I open the box will the gas expand?

[Colin2B]

Yes.
Crack a can of beer, hissss escaping gas.

[guest39538]

Yes.

Thank you Colin, if we had a low pressure of gas inside the box and polarised the gas, would the low pressure become high pressure because the gas would expand?

[Bored chemist]

and polarised the gas,

What do you think the word "polarised" means today?
It would probably be best if you can cite some sort of dictionary,r rather than making up nonsense.

PHYSICS
cause (something) to acquire polarity.  maybe i should of spelt it polerized,

[Bored chemist]

Thanks for ruling out political polarisation.
But that hardly limits things...
Here's what WIKI says
Polarity may refer to:

In science:

Polarity (mutual inductance)
Polarity (physics), a physical alignment of atoms
Cell polarity, differences in the shape, structure, and function of cells
Chemical polarity, a concept in chemistry which describes how equally bonding electrons are shared between atoms
Polar reciprocation, a concept in geometry also known as polarity
Trilinear polarity, a concept in geometry of the triangle
Electrical polarity
Polarity in embryogenesis
Polarity (projective geometry)

Being obtuse I see.   

Ok, I will rephrase the question, if the contents of the box were to become ionised and became Cations, would the contents expand?

[Bored chemist]

" if the contents of the box were to become ionised and became Cations, would the contents expand?"
OK, two things.
Did you mean "polarised" or did you mean "ionised"?
Second,
This
"if the contents of the box were to become ionised and became Cations, "
 is impossible- because it would be a breach of charge conservation.

It's not that I'm being obtuse, it's that what you say doesn't make sense.

In before he tries to argue that electrons are somehow analogous to this box of charged gas and therefore should expand...

I know.
He didn't make much sense then either.
I'm hoping that this time he might, at lest, tell us what he thinks he's proposing to do but at the moment it's  something like this

, if we had a low pressure of gas inside the box and did magic , would the low pressure become high pressure because the gas would expand?

[guest39538]

Quite clearly you have poor abilities in imaginary concept to devise proper concepts.

Ok, if I had a magic box that contains electrons, would these electrons pressure the box by expanding in length apart?

[Bored chemist]

expanding in length

Electrons don't have length.
Will you please try to frame your questions so that they are in the realms of science.

[guest39538]

Your being a troll, it say expand in length between the electrons. 

[Bored chemist]

say expand in length between the electrons.

And combining those we get

Ok, if I had a magic box that contains electrons, would these electrons pressure the box by expanding in length
 expand in length between the electrons apart?
which is still gibberish.

Why don't you take your time, and work out what question you are actually trying to ask?

Do you mean this?
"If you had a box full of electrons, would they exert an outward force on the walls of the box?"

[guest39538]

"If you had a box full of electrons, would they exert an outward force on the walls of the box?"

That is what I said......

[Bored chemist]

"If you had a box full of electrons, would they exert an outward force on the walls of the box?"

Anyone who reads the thread will realise that it is not what you said.
And the answer is...
It depends.
For a start I guess we assume that the box is made of some magic stuff that electrons bounce off.
For a perfectly  insulating box the answer is yes.
For a box that conducts the answer is No  (I think), but it may depend on the temperature of the electrons.

Somehow I don't see this model is going to get us very far.
It's not a physically valid model of the real world.

[guest39538]

For a start I guess we assume that the box is made of some magic stuff that electrons bounce off.
For a perfectly  insulating box the answer is yes.

Well eventually the question was answered.   


So you say yes to what I have quoted.  So what will happen to these electrons if we opened the magic box?

1)  They stay in the box?

2)  They expand out of the box?

[Bored chemist]

It depends.
The "electron in a 1 dimensional box" model is quite commonly used as an example while teaching quantum mechanics.
and the "real life example" of it is a box which is inside the electrons.
Yes, I wrote that the right way round.

That was avoiding the question, but ok,  A box inside an electron , I presume this box has dimensions?   

So if all the integer points of the box are electron points, what should happen to these points ? 

Considering your earlier answer of yes

For a start I guess we assume that the box is made of some magic stuff that electrons bounce off.
For a perfectly  insulating box the answer is yes.

Supposing I said that the magic box that stops the electrons expanding is a magic box made of protons.

Your yes answer would also be true for a magic box of protons?


What happens if we put protons and electrons in the box, does one stop the other expanding ?

[alancalverd]

You might corral a bunch of charged particles with a magnetic field. On release, particles with like charges will repel each other so the cloud will expand. The practical problem with plasma physics is that it is actually more difficult than herding cats.
