Answer 2

What Is Argon Used For

Answer 3

Argon is a gas, not a metal. The only time I've used argon is during welding, where the argon acts as a shield to keep impurities out of the weld.

Answer 4

Argon is used for a few things such as in fluorescent light bulbs to help create brightness, and also some lasers use an argon based gas, such as Excimer lasers used in Laser eye surgery use an Argon/Fluorine based gas.

Answer 5

Argon is an inert gas. Used extensively in welding

Answer 7

There are several methods to improve quickly and naturally eye sight.
To know how to do that you can find here a complete method based on researches done by some scientist, for a cheap price ( http://getyourvisionbacknow.keysolve.net )

I can give you just some tips but I suggest to give a look to the method that i posted above, for example you can take more food that contains vitamin A such as carrots may help to naturally improve your eye sight.
We can also always do exercises. There are exercises such as rolling your eyeball to form an invisible square that are always recommended by the doctors to improve one's eyesight.
I don't know about quickly as there is no fast way to reach one's goal.

Vegetarians can help to improve one's eye sight. I believe it because I am a vegetarian and my eye short-sightedness power remains the same without any increase after about 2 years.
The doctor was shocked because teenagers at my years will usually have a most increase since we are always watching TV, playing computers and also reading.
I do not know whether it is totally true or not but it does affect a bit on the result.

Answer 8

Argon is a noble gas,like xenon,radon, neon, krypton and helium.Argon is used in neon lighting to create a wider range of colors than neon can.

Answer 9

Argon is used in incandescent lighting and other applications in which diatomic nitrogen is not sufficiently inert. Argon will not react with the filament of lightbulbs even at high temperatures. Other uses:

Argon is used as an inert gas shield in many forms of welding, including metal inert gas welding and tungsten inert gas welding.
as the gas of choice for the plasma used in ICP Spectroscopy.
as a non-reactive blanket in the manufacture of titanium and other reactive elements.
as a protective atmosphere for growing silicon and germanium crystals.
as a gas for use in plasma globes.
as a gas for thermal insulation in energy efficient windows.
Argon-39 has been used for a number of applications, primarily ice coring. It has also been used for ground water dating.
Cryosurgery procedures such as cryoablation use liquified argon to destroy cancer cells.
Liquid argon is used in calorimetry in experimental particle physics.
Argon is used in technical Scuba diving to inflate the dry suit, because it is inert and has low thermal conductivity.
Blue argon lasers are used in surgery to weld arteries, destroy tumors, and to correct eye defects.
Due to its inert qualities, it is commonly used by museum conservators to protect old materials or documents, which are prone to gradual oxidisation in the presence of air.
Argon is used in the tires of luxury cars to protect the rubber from oxygen and to ensure quiet tires when the car moves at fast speeds.

Answer 10

Argon is a noble gas i.e. it is highly unreactive. It is used to fill light bulbs (due to its unreactivity). This prevents the tungsten filament from oxidising.
