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!
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.
How the filament in electric bulb is made burning?
Resistive Heating, as current passes through the filament power is dissipated from the filament in the form of heat, they are made of Tungsten which has a melting point of 3380 degree Celsius. And since the interior of the bulb contains very little to no oxygen, usually filled with argon or similar type gas. The filament cannot burn, but will degrade over time to the point where it "burns out" but in reality the filament just breaks
Why is argon used instead on air in the light bulb?
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.
What is inside light?
For Light bulbs:The filament is made of tungsten. There is a inert gas used around the filament which is usually argon, neon, or nitrogen.
Which gas in the air is needed for a filament to burn?
Oxygen

Which gas in the air reacts with the wax as it burns?
oxygen
One of the gases released into the air when fosil fuel burns?
gas gas
What gas is used inside the bulbs?
Assuming the question is referring to incandescent light bulbs (the ones with the glowing filament), Argon is the gas used.Argon is a harmless gas found in air, and is used because it cannot react with the hot filament.
Why the central blue cone in the blue flame is unburnt gas?
because no air enters it. The air burns gas.
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.
What is the gas in the gas taps and comes from under the north sea. It burns with a blue flame if there is plenty of air?
methane is in gas taps comes fro under the north sea and burns with a blue flame if there is plenty of air from gemma
If a natural gas line is ignited does it burn back to the source of the gas?
it only burns in the air
Gas formed when sulfur burns in air?
Sulfur dioxide, SO2
Which gas in the air is used when icing sugar burns?
Oxygen.
What colorless gas burns with oxygen?
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.
