i learned about this in chem.  it's hard to explain...but if you put a cd in your microwave(if your parents allow u 2) then you can see it.  if u need help, you could e-mail my teacher by getting his e-mail address from his website below.  hope that helps!

many fluids have a bit of cohesive strength. their molecules stick together. we can really see this in slime. plasma tends to stick together. even better than water, which has hydrogen bonding to help make it cohesive. it's how water gets up the stem of a plant.

If you mean plasma cutter, I can help.  A plasma cutter puts a high-frequency (RF) pulse from the copper tool tip to the metallic material to be cut.  This ionizes the air.  Then DC power is delivered to the arc.  The machine dumps a lot of power into the material, heating it up.  The small opening in the tip is for air which blows the molten material away.  In the case of aluminum, the air just pushes it out of the way.  In the case of steel, the air charge reacts with the iron to produce iron oxide, which further produces more heat than just the arc and helps cut the material.\n\nTraditional gas cutting with acetylene and Oxygen is similar, although i have never gas-cut aluminimum.  (?)  The oxy-acetylene is set up to heat the steel with a blue flame.  When a spot is melted through, you push the oxygen lever which lets a lot of oxygen out right onto the metal.  The ferrous (iron) material burns with the oxygen, cutting the steel.

Good question.\n\nI can't answer it here, it would take to long, but I suggest you go to this web site:\nhttp://www.iter.org/a/index_use_1.htm\nthen click the link to read more under intro to fusion.\nThen go to fusion as an energy source click read more, and then click how.\n\nThis page does a good job on explaining the basics of a plasma confinement. If you have more specific question feel free to ask.

Plasma is a state of matter when the bonds between molecular particles are broken and subatomic particles are all lumped in together. This condition of matter is achieved under extreme temperatures and pressures, typically in stars. Most of the mass of our Sun is composed of plasma matter also.

u see,when a solid is heated to a certain extent it melts into liquid,and further heated it becomes a vapour,when it is heated to a greater extent,the molecules break up into atoms and atoms into very minute states.these form a cloud of particles which is called plasma.\n          for ex.,the temp. of stars is upto millions of degrees hence the plasma is present and also known as fourth state of matter.\n        i hope u got it!!!

The 4th state:\nThe 4th state of matter is called the plasma state, which is (in simple words) made of charged particles like electrons and ions. All ordinary stars are in the plasma state.\nThe 5th state:\nBeautiful filament-systems are often shown by the astonishing development of the modern astronomy. Most of these filaments have an exact circular cross section. Filaments have the same interesting characteristics from a diameter of 0.01 mm to that of many 1000 of light-years. Filaments are incorrectly seen to be of plasma, however, particles move in only one direction in them, often against gravity. In this non-thermal (fifth-) state of matter, particles have up to (10 to the power 16) -times higher energy than those in the hottest stellar plasma. The corona-problem and hundreds of other problems of astrophysics are solved at once.\nOnly six states of matter are possible (the zeroth state is of course the Bose-Einstein condensate state)!

I don't completely understand your question.\n\nPlasma is the fourth state of matter, neither solid nor liquid nor gas. It sort of plays by it's own rules. In essence, plasma is an gas (Argon for example) that is excited to a higher energy level by the application of some external stimulus. Case in point would be a welder's gas shielded welding torch, in which a gas (Argon or CO2) is fed through a hose to the torch nozzle. The gas is energized by an RF current that flows through the hose assembly in addition to a heavy direct current to provide heat. The gas ionizes, creating a plasma, and when expelled from the torch, functions as a shield to protect the molten metal from contamination by our atmosphere until it solidifies. \n\nThe main function of a plasma in other industrial context is to provide heat. I have heard that a plasma (lightning for instance) can achieve temperatures nearly six times the surface temperature of our sun. A plasma cutting torch, as I understand it uses the heat of a plasma to heat the work surface to the melting point after which a cut is made by blowing compressed gas through the metal. A rapid non-combustion method of cutting steel.\n\nA flame is also a plasma. In industrial applications, a flame from a pilot burner (in a boiler for example) will allow electricity to only flow through it in one direction, much like a solid state diode. If one places two probes into a flame but separated from each other, and impresses an alternating current on one, a direct current will be received from the other when a flame is present, thereby proving the existance of a pilot flame before the main burner is allowed to operate. \n\nHope this helps\n\nOuzinki

No...\nI don't know what it would be but I would not guess a plasma...

That's a tough question. Many plasma tv's are HDTV.\n\nYou have to look at two dimensions. The display technology: Plasma, LCD, DLP. Generally each has its own weakness and strength.\n\nand HD Compatibility. HD Compatibility generally falls into three categories: non compatible, HD Ready, and HDTV Tuner. HD Ready means that the TV will display a picture in HD but requires a box to decode the signal. HDTV Tuner usually has the decoder inside and does not require a box to decode. Usually these TV's accept cards from cable providers to give you access to cable.\n\nI've posted a few links that might help with the display technology question.

Blood plasma is the liquid component of blood, in which the blood cells are suspended. Serum is the same as blood plasma except that clotting factors (such as fibrin) have been removed. Blood plasma contains fibrinogen.\n\nPlasma resembles whey in appearance (transparent with a faint straw colour). It is mainly composed of water, blood proteins, and inorganic electrolytes. It serves as transport medium for glucose, lipids, hormones, metabolic end products, carbon dioxide and oxygen. (Oxygen transport capacity of plasma is much lower than that of the hemoglobin in the red blood cells; it may increase under hyperbaric conditions.) Plasma is the storage and transport of clotting factors and its protein content is necessary to maintain the oncotic pressure of the blood.\nhttp://en.wikipedia.org/wiki/Blood_plasma

Its like getting your blood removed... Plasma=whole blood - blood cells. Plasma gives volume to blood, makes it fluid and allows blood cells to circulate (among other numerous functions). Loss of body liquids thickens blood by lowering the volume of plasma (which consists primarily of water), and thats how people die from dehydration... or vampire bites ;)

well lcd lasts longer but plasma is visualy better, they both have upsides.

Q:What would be the soonest fusion power could be operable in Europe if funding were increased, and energy funding diverted from fossil fuel energy research, and finally, if the fusion research projects of the USA, EU, and Japan were combined, what is the soonest fusion power could be efficiently operated?\nA: The next step from JET (and the other tokamak research being undertaken around the world) is a device called ITER, an international tokamak project, 2-3 times bigger than JET, costing several billion pounds and capable of producing significantly more fusion power for longer periods. This will demonstrate the feasibility of the plasma physics and fusion engineering of a potential power plant and, given the present funding, is planned to be built in the next 10-15 years - an eventual commercial power plant probably being 30-40 years away. However, if the present international funding for fusion were increased, ITER could definitely be built more quickly and fusion power could be a reality much more quickly - in possibly half the time if the present funding levels were increased significantly.\n\n \n \n \nQ: What developments in fusion technology are likely to take place in the future, say 10, 20 years from now? \nA: The next step device following on from JET (called ITER) is currently being designed and should be operational in 2020. This will demonstrate burning plasmas (with Q ~ 10 where Q is the ratio of the output fusion power and the input power required to keep the plasma going) whereas JET has achieved Q~0.6. It is then anticipated that a working, electricity producing reactor should be
