What gas that is found in the air which is needed for the toast to burn?
Burning release carbon dioxide and water vapors.
Why do bulb filament not burn?
The filament does not "burn", it just glows brightly. If some air were present in the bulb - as sometimes happens if a light bulb gets knocked and gets even a tiny crack in its glass bulb - then the oxygen present in ordinary air will quickly make the filament burn away.For more information see the answer to the Related question sghown below.
Is all the air vacuumed out of a light bulb or is special air pumped in?
The filament (assuming an incandescent bulb) would burn up very quickly.
How is light produced in an ordinary incandescent bulb?
Electric power is put trough a metallic filament inside a bulb that is filled with an inert gas. the filament is surrounded by the inert gas rather then air to stop the metallic filament from oxidizing when it starts to glow as a result of the electricity being run through it. the glowing filament produces the light.
A colourless gas in trace amounts of air?
Helium is a light colourless gas that does not burn
Which gas in the air burn's out the filament?
Oxygen
What gas in the air is needed for something to burn?
Oxygen is needed to feed the flame.
In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?
It won't burn the filament.
Why is there argon gas in the light blub and not air?
The hot filament of a light bulb would quickly burn away if it came in contact with oxygen from the air. Argon is inert and so will not react with the filament, even at extremely high temperatures.
Do you burn more gas with your air conditioner on?
Do you burn gas when you run your air conditioning in your cae
What gas that is found in the air which is needed for the toast to burn?
Burning release carbon dioxide and water vapors.
What do you use argon gas for?
As an inert gas, argon is used for shielding very hot metals from the air. Very hot metals, such as the filament in a lighbulb, would react with oxygen and burn in a second or two. The argon gas in the lightbulb keeps that from happening.
Light bulbs last longer when they are filled with what gas?
Incandescent light bulbs need to have an inert gas or a vacuum to prevent the filament from being surrounded by air (with oxygen) which would enable the filament to catch fire and burn. Inert gases used include argon, krypton and nitrogen or some combination of them.
Which gas in the air is needed for fuels to burn?
oxygen is needed for fuel to burn
Why is there hardly any air in a glass bulb?
Hi! This is the question for this question! Because air was contained with oxygen and oxygen so oxygen with smallest heat it burns down the filament! This is also evacuated and filled with a gas which does not react with the red hot filament. So .... if air present the filament would quickly oxidise and fail to light up!
What gas is needed to burn paper?

Which gas is needed for a candel to burn?
