Plasmas don't have to be hot. The definining characteristic of plasmas is that they are ionized. Ionization can occur at any physically realizable temperature, although heat certainly does help ionization occur. With regard to an ultracold plasma ... its ultracold, hence the name. 1 million Kelvins (your interpretation of 1mK) is not cold. 1 million Kelvins is 1MK, not 1mk. Our sun's core has a temperature of about 13 or 14 MK and its outer atmosphere, about 1MK. The photosphere, still a plasma, is only 6000 Kelvins. If 1MK qualifies as ultracold, what does that make 6000 Kelvins? A lower case "m" means milli (1e-3). 1 mK is 0.001 Kelvins. Now that is cold.
>> Plasmas don't have to be hot at last, someone who knows what they are talking about. Now if all matter is a plasma, then all matter is in a state where it has intrinsic static electric charge, and because all these charges are in motion, then all matter also has an intrinsic magnetic charge. We traditionally class the electron as electric and the neutron/proton as magnetic. From these two orthogonal forces, the world is made. Therefore the various "states" of matter we experience all depend upon the level of extraneous energy.
Unfortunately, that is not you. All matter is not plasma. End of story. An ultrcacold plasma has all of the characteristics of a plasma -- its an ionized gas. The ground you stand on is not a gas; its not a plasma.
>> All matter is not plasma. OK, but I disagree.... keep on putting new names on the same things if you like... it will just lead to confusion... as is evident in this thread.... Just because humans first found "ground" solid matter, does not mean that that stuff is not the same as 99% of the Universe,,,,,,,, The Universe is only made of a few building blocks, IMO. Best keep the number of "names" to a minimum.
URI, what the hell did you just say? Dictionary.com Plasma # Physics. An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. It is a phase of matter distinct from solids, liquids, and normal gases. End of story
URI: Again, and again, and again, A plasma is a phase of matter. It is not a solid, liquid, or a normal gas state. A plasma is an ionized gas state. And in that ionized gas state, in order for it to be considered as a plasma, an electron has been removed to make it a positively charged particle or molecule. This is what gives it a positively charged electric conductivity and a potential possibility of becoming an electromagnetic field.
http://www.plasmacosmology.net/imp.html >> Standard scientific texts focus on just three states of matter -- solids, liquids, and gases. This is no small omission. Not only should Plasma be added to this list, but it should take first place, not least because of the fact that it constitutes 99% of the known Universe! Space travel has confirmed this fact. It is misleading to describe plasma as an ionized gas when it is in fact a state in its own right. Given the dominance of Plasma in the universe, it seems more sensible to consider solids as cooled Plasma (Or matter with energy removed), as opposed to highly energised or heated matter. Moreover, because of the ability of Plasma to interact with electromagnetic forces, it is capable of forming far more complex structures than those seen in solids, liquids, or gases. >>> yes !
