Right,

Being a Nobel gas, it doesnt usually combine with any other elements.

Price? Looks like about $8.31 for 100 cubic feet.

geographical source: Extracted from the atmosphere.
Air, is compressed, and cooled to form liquid air.
Each gas has a different boiling point, so gases like Helium are extracted first, then heavier gases boil off at higher temperatures.
The process is called fractional distillation. This is also how other gases are extracted, like Zenon, Krypton, liquid oxygen, liquid nitrogen, etc.

" Argon is very inert and is not known to form true chemical compounds. "

>>Common ores and compounds: None

Almost all regular light bulbs, and Florescent bulbs are filled with low pressure Argon as mentioned, to displace the oxygen, and to provide low pressure. The Tungsten filament will eventually shed some of its atoms due to the extreem temperature.
The pressure provided by the Argon, helps to keep the filament from evaporating.

What is Temperature?
Temperature is the measure of molecular vibration. Hot atoms are shaking to pieces, and atoms cooled to the point where all molecular vibration has stopped, is at absolute zero.
Absolute zero is -273.15C (Centigrade), also known as 0 Kelvin.
The Kelvin scale starts at absolute zero, and is identical to the Centrigrade scale, except it is shifted to begin at absolute zero.
0 C is +273.15K, 0C = 32F C= (F - 32) *( 5/9).


Water will boil if it gets too hot ( molecules shake too much and overcome the weak bond holding it as water). The hotter ( faster ) molecules get blown away if there is a breeze, leaving cooler molecules behind ( why alcohol evaporating on your hand feels cool).


Other tubes are filled with Zenon ( flash cameras), and Neon, in the long Neon lights, and Krypton is expensive flash lights and some automotive headlights.
The lamps designed for higher operating pressure, can run hotter, making a more natural ( blue-er) light, without the filament evaporating. Sort of how a pressure cooker allows the water to boil at a higher temperature by applying pressure.
The boiling point of water is dependent on atmospheric pressure.
The higher the pressure, the higher the boilling point. Up on top of a mountain, water boils at a lower temperature making it harder to cook food. Water in a vaccuum will boil at a low temperature.

Argon is an inert gas that makes up about 1% of our atmosphere. I don't know where you would but any.They put in lightbulbs under low pressure to get rid of the oxygen that would cause the filament to burn.
