Nitrogen is preferred over air for the atmosphere around an incandescent light source because nitrogen is less likely than oxygen, the other major constituent of air, to react with whatever material, usually a metal, constitutes the light source. As a result, the "burning out" of the bulb is retarded and less frequent replacement is necessary. Some expensive incandescent bulbs in very critical uses are filled with argon, which is even less likely to react with the light source.

Which gas is used in electric bulbs?

Incandescent light bulbs use a combination of gases: argon and nitrogen. These gases help prevent the filament inside the bulb from evaporating too quickly, increasing the bulb's lifespan. LED bulbs do not use gas but instead rely on semiconductor technology to produce light.


Why does the gas liquid nitrogen have these use?

because most of our atmosphere has nitrogen in it


Nitrogen-fixing bacteria get nitrogen from?

Nitrogen-fixing bacteria get nitrogen from the atmosphere, specifically from nitrogen gas (N2). They convert this nitrogen gas into a form that plants can use, such as ammonia or nitrate, through a process called nitrogen fixation.


During nitrogen fixation nitrogen gas is converted into a form that what can use?

During nitrogen fixation, nitrogen gas is converted into ammonia or other forms of usable nitrogen by nitrogen-fixing bacteria. This process is important because plants and other organisms cannot use atmospheric nitrogen directly in this form.


What does the nitrogen inside a light bulb do?

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.


This gas is used in a light bullb?

The most common gas to fill light bulbs with is a mixture of Argon (~93%) - which makes up about 1% of the atmosphere and is inert, and Nitrogen (~7%) - which is about 78% of the atmosphere and which makes the gas mixture less conductive to prevent arcing. Some specialty bulb use pure nitrogen, pure krypton, krypton/xenon mixture, or vacuum (no gas at all).


Do most organisms use nitrogen in the form of nitrogen gas?

No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.


Do humans use nitrogen gas?

Yes, humans do use nitrogen gas for various applications such as in food packaging, semiconductor manufacturing, and as a coolant in some industries. However, we do not breathe nitrogen gas as it does not play a direct role in sustaining human life.


Process in which nitrogen is released into the air and soil?

Nitrogen fixation is the process by which nitrogen gas is converted into a form that plants can use, predominantly by nitrogen-fixing bacteria. Denitrification is the process by which nitrogen is released from soil back into the atmosphere in the form of nitrogen gas.


Why is nitrogen gas in the atmosphere useless to plants?

Plants cannot use nitrogen gas directly because they lack the necessary enzymes to convert atmospheric nitrogen gas (N2) into a usable form like ammonia (NH3) or nitrate (NO3-). Instead, plants rely on specialized bacteria in the soil called nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that plants can use for growth.


What is meant by nitrogen fixation state two ways in which nitrogen gas of the atmosphere can be fixed in nature to get nitrogen compound in the soil?

Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.


What converts nitrogen into air plants can use?

Nitrogen-fixing bacteria convert nitrogen gas from the air into a form that plants can use, called ammonia. These bacteria form symbiotic relationships with certain plants, such as legumes, providing them with a source of nitrogen for growth and development.
