If Neon gas can be ionised by passing a high voltage through it, what is the effect if the gas is compressed?

It can still be ionised.

A "true" neon light will have clear glass, if you want to get the specific frequencies that Neon plasma produces.\n\nYou friend's light may have neon gas inside, (impossible to tell), but you don't want it if you want to see what neon light looks like.

Same principle as neon lighting.  With a neon light you have a gas with current passing through it causing it to emit off a light.  In this case it sounds like a concentration of whatever the specific gas happened to be in the air at the lightning strike, and what you saw was the gas emitting it's light.  Anyone happen to know what gas gives off green light in neon lights?

plasma is the highly ionised gases.\n\n We know that ionised gas can conduct electricity.\n\n According to Farrady's law when ever there is a change in magnetic field emf is induced.\nThere is a method called "MAGNETO HYDRODYNAMIC"  in which a magnet is placed over which a hot ionised gases(plasma) is sprayed through a nozzle, so according to our law there is a change in magnetic field due to relative motion between magnet and ionised gas(plasma).... thus EMF is induced.\n \nBut there is a problem.... To create ionised gas we have to heat the gas for more than 10000 degree celcius, But there is no metal which can withstand this much temperature, so to overcome this some materials called as SEED is added which will be ionised easily..... \n\nFor more information you better refer "Power plant engineering" book by R.K.Rajput.......

dont do it man. if you put co2 into a compressed air/nitrogen gun, it can freeze up the internals, and that is an expensive fix. compressed air runs a lot nicer through the marker, and doesnt have to worry about changing its form so often (liquid, gas). compressed air is straight gas the entire way, and it a lot easier on the gun.

Well. Okay its like this. Most times a chemical in a can is gas, but while its in the can its liquid. This is because of pressure. It pressurizes it to a point of where it would be if it were really cold. When something that is a gas at room temperature is cold, say below freezing, it would be liquid. When its compressed to a liqid state it is going to be cold. I hope this makes sense. Instant message me if it doesnt and ill explain more.

Well, the elements in column 1 when ionized have a +1 charge. The elements in column 2 have a +2 charge when ionized. The elements in column 7 when ionized have a -1 charge, and the column 6 elements form -2 charged ions.\n\nThe column 8 elements are called noble gases, because they have a full valence shell of electrons and don't bond readily with anything. They don't normally ionize.

Someone has used a gasifier and captive-piston engine to make a one-moving part alternating-current generator. The piston is magnetized and the coils are in the body of the cylinder. The trapped air in the cylinder at each end of the piston acts as an air shock to eliminate rebound and impact damage. No sensors needed. No make and break circuit. The voltage drops to zero at the end-points of travel of the piston. Search on this and you can probably find the same one I saw. I think this is where they got the idea for those new shake-up LED flashlights.

As I understand it-- the electricity agitates the electrons of the gas- the color is from the color the maker coats the inside of the tube with.

well since o2- has an extra 2 electrons it gives it 10 electrons total making it the same electron configuration as neon which is a noble gas....so the elec. config for o2- is [Ne]

By tube lamps I will make the assumption you are talking about Neon tubes.  Generally, Neon tubes are a combination of Neon and Helium with a small amount of Mercury in them.  The inside of the class is coated with white phosphor.  \n\nThe basis of operation is a high voltage transformer is used to cause the Neon gas to rise in energy level to the point it forms a plasma.  This is kind of like a spark that causes  the neon to suddenly glow, the energy emitted by the Neon is then absorbed by the phosphorous and re-emitted as a blueish white light.\n\nTo get the process started requires a higher amount of current then is available from the transformer and in older lamps a capacitor is used as a starter.  This capacitor charges up and then provides the current to get the Neon to start to glow originally.\n\nGenerally, the Neon lamps will only rise to the energy level in the presence of this high voltage from the transformer; however, I have seen cases in which either lightning or High energy radio waves can raise the energy level enough to cause them to begin to glow at a low level.  Generally the wires that are connected to the ends act as antennas and external energy radiated can be enough to cause the Neon to glow.\n\nIn failing neon tubes sometimes a conducting track begins to form on the inside of the lamp moving the conductor ends closer together, if the capacitors are not discharged it is possible that you might see a glow a second or two after the power has been shut off.  The you have another case in which the tube is already failed in that the anodes in the ends of the lamp tubes have broken down and the Neon does not rise in level required to glow.  And though they look like the power is off it is still on only there is not enough power reaching the gas in the tube to cause it to glow.  However, due to random heating or metallic vapor in the tube it is possible that the tubes will start to glow once in a while.\n\nDave Cooke

I don't like the term "easily", because that's vague. Gases can be compressed, as people have noted, because the space between gas molecules is large but unoccupied. However, you do have to perform work in order to compress a gas (thereby using energy).

When you compress the spring, you distort the lattices of the crystals that make it up.  The potential energy is stored in the chemical bonds between atoms in the lattices.\n\nIf these bonds were broken, the atoms would still have the same energies, but would no longer be tied into a crystal.  Their potential energy would become the kinetic energy of motion.  The kinetic energy of atoms and molecules is measured by their temperature.  \n\nFormerly metallic solid spring would become a hot gas.  In other words, the potential energy would be converted to kinetic energy (high temperature) and you would see an explosion.

Friction in some materials causes electrons to be knocked free, resulting in a buildup of negative charge.  Enough of that builds up in your clothing and it's going to want to equalize itself by going to ground - a doorknob for example.  It gets there through your finger.  Static electricity shocks are basically a scaled-down version of what happens when lightning hits the earth.

The pressure between the inside of the can and the outside will equalize. It won't blow up in the sense of destroying the can. What might happen is that the metal near the puncture will tear a bit as the escaping gas rushes past it- in the same way a hole in a dam would 'grow' as water flows through it.\n\nProbably of more interest is that the escaping gas will be at a much, much colder temperature as it expands. This can lead to a surprising freezing effect at, on and near the can.\n\nIt is much more dangerous to heat a pressurized can without puncturing it. In this case, the can can fail as the pressure increases (due to the heating) and burst along a large seam instead of a small hole. Pieces of the can can be ejected quite powerfully in this scenario. The puncture scenario doesn't give you this effect at all.

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

Anything that is electrically charged, such as most "natural" substances (pollen, dust, dander, etc-and smoke particles).  Most polluting gases, such as sulpher, carbon monoxide, etc, would not be effected.  From the tone of the question, I have to assume this is a person with some breathing difficulty due to environmental reaction- in that case, most of the offending substances would be removed or reduced by electrostatic purification.  They work much more effieciently if you have an ionizer as well, which increases the charge density on particles.
