Absolute Zero Gas: Is Motion Possible?

[heavystray]

What happen to gas particles at absolute zero?
Is it possible that the particles will still be moving ?
Thanks in advance

Read up on Bose-Einstein Condensates.

Is this a homework question?

The homework question is acctually a bit different. It says what is the characteristics of gas particles at absolute zero.
I read some articles that say the gas particles will stop moving

No. If they stopped moving they would violate HUP. What happens is that the atoms "smear out" into what's called Bose-Einstein Condensate.
Basically, the more their movement becomes known (i.e. approaches zero) the more their position becomes unknown (they smear out).
