At what temperature does gas become plasma?

Question

Wikipedia has some excellent info, but doesn't cover some details I need, such as this one. Could I get a layman's answer, since physics principles are a bit over my head?

Thanks for the initial reply. I guess these questions may help define the first one: How does a plasma chamber work? At what temp can plasma be produced in this context? Ex: the chamber at UCLA or U of I?

Answer 1

It depends on species and density, but generally about 10,000 C.

Answer 2

It depends on the element. Just as elements have different melting and boiling points, so do they have temperatures at which they turn into plasma.
