Why is argon used in a light bulb instead of air?

The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.

Argon can be used in bulbs much like neon can; where neon gives off a reddish-orange light, argon is a bluish tint. If argon is used in an incandescent bulb it's probably to protect the filament from oxygen in the air. However, I'm not sure this is ever actually done; I know nitrogen is sometimes used for this purpose, but using argon seems to be overkill.

argon is no reactive how ever vacuum

because the oxygen in air would burn causing the light bulb to burn out very quickly.

Noble gases are used in light bulbs because of their properties. For example, argon prevents tungsten filaments from evaporating. Thus, argon increases the life of the light bulb.

There are various elements that are found in a light bulb. Some of the elements include the filament, fill gas which is commonly mercury or argon and iodine which is used in halogen bulbs.

Argon is often used when an inert atmosphere is needed. It is used in this way to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury. When it is switched on an electric discharge passes through the gas, generating UV light. The coating on the inside surface of…

yes. filament will burn though less fast hope you find this useful

An energy saving light bulb is simply a fluorescent light-bulb in a small housing with a built in starter . The gas used for it will be the same as a standard strip-light which is a tube filled with low pressure mercuric oxide and an inert gas like Argon Neon or krypton.

Light bulbs are filled with argon AND nitrogen because they don't burn up the light bulb as quickly. It take a high tempertaure in a light bulb to create the light. The heat in the light bulb then causes chemical reactions. If there was just air in a light bulb, then the element would quickly react with the oxidize (oxygen) and burn out the light bulb. Now, with the light bulb filled with argon and…

the gas used in these light signs are neon and argon the gas used in these light signs are neon and argon

Argon does not react. :)

Argon is an inert gas that will not support burning when the bulbs filament becomes white hot because of the current running through it. When a light bulb consists of tungsten, when electricity is passed through it, tungsten offers a very high resistance and it becomes hot and produces white light. At this temperature when it is exposed to air, tungsten gets oxidized. So prevent its oxidation, tungsten is burnt in the atmosphere of argon…

An inert gas such as argon is used to fill inside in an electric bulb. The filament of a bulb is made by the metal, tungsten.

where was the first light bulb used

Incandescent light ,

Argon is used in situations where materials need to be protected from oxygen or other gases. A good example is an incandescent light bulb, which consists of a metal wire inside a clear glass bulb. An electric current passes through the wire, causing it to get very hot and give off light. Oxygen will combine with the hot metal very easily, forming a compound of the metal and oxygen. This compound will not conduct an…

Different kinds of light bulbs used different gasses. The incandescent bulb uses no gas - it uses a vacuum. Other kinds of bulbs may use nitrogen, argon, neon, or krypton.

The gas that is normally used is argon, or a mixture of argon and nitrogen. A gas is needed that • helps prevent the evaporation of white-hot tungsten • does not react with white-hot tungsten • will not form an electric arc inside the bulb Argon is the cheapest of the noble gases because it forms nearly 1% of the atmosphere, and is a major by-product in the production of liquid nitrogen.

one is a screw at the end of a light bulb

Light bulbs. i think

Wattage or Watt is the unit used to measure a light bulb....

The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.

Thomas Edison invented the first light bulb that was available for commercial use in 1879. The light bulb was first used in Menlo Park.

neon and argon

Neon, argon,

Candles were one source of lighting before electric light bulb was invented.

Neon and argon are used in lighting.

its used for light bulbs, radio tubes, and welding.

Edison perfected the light bulb by refining the filament. He used tungsten

The gas used in fluorescent lamps is argon. Also are used sodium vapors lamps (yellow light). The incandescent lamps have 93 % argon and 7 % nitrogen. Neon is used for red lamps.

The only power used by a desk light is that used by the bulb. The bulb normally has its power in watts marked on it.

No. Propylene is oxidised in presence of oxygen and the reaction is exothermic. The heat generated is used in welding. Argon is chemically inert and will not result in combustion.

Uranium is not used in light bulbs.

he used many different threads, he made the first light bulb with horse's tail hair.

That can vary A LOT, depending on the specific technology used (the type of light bulb), and the brand.

Argon is in incandescent light bulbs, but neon lights actually have different gases to product the different colors. Neon, krypton,argon

Argon is used to produce violet lights. Electrons in argon atoms use energy from the firework explosion to make the transition from the ground state to an excited state. Their return to the ground state results in the emission of violet light.

The original Edison light bulb used a carbon based filament, later a metallic filament (tungsten) was used to increase the life of the bulb. Today the government has mandated that a fluorescent type bulb be used

Rear combination light assembly contains three bulbs. Two bulbs are single-filament and are used in hazard/turn signal and backup light circuits. Third bulb is a dual filament bulb; one filament functions as brake light and other as tail light. A plastic bulb holder mounts three lamps and associated wiring. Bulb holder can be removed from inside vehicle for bulb replacement.

There are several different gases which are used in light bulbs. Some of those gases are neon, argon, nitrogen, and xenon.

Argon is used in light bulbs because it is the most common noble gas.

Yes, modern incandescent bulbs are filled with an inert gas (argon,) but with a bit of nitrogen. Nitrogen is used because argon supports long sparks and leads to electric arcs and exploding light bulbs, and nitrogen interferes with this effect.

In most home wiring circuits, the black wire is used to power a light bulb. The other wire is white and is called the neutral conductor.

Modern light bulbs don't hold a vacuum. Instead they are filled with an inert (electrically non-conducting) gas such as Nitrogen. An inert gas is used to fill the bulb (instead of just pumping out almost all the ordinary air to leave a near-vacuum) because the action of filling the bulb with an inert gas flushes away ALL of the ordinary air. In addition the inert gas has the very useful physical property of helping to…

Electricity is the type of energy that is used when you turn on a light bulb. When you leave a room, you use more energy by leaving the light on than if you turn it off and back on when you return.

Air - the kind we breathe - contains oxygen. oxygen can sustain combustion. A filament heated to glowing in an oxygen atmosphere would burn up. Argon - and some other noble gases - don't sustain combustion, so won't make the glowing filament burn.

Using a remote control similar to those ones used to turn on electronic devices. The infrared rays can switch the light bulb on, since it has a small transistorised circuit that can actuate a tiny relay to put the light bulb in series with the electric circuit.
