What is the hot filament protected by?
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
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?
Argon is used in light bulbs because it is an inert gas, which means it does not react with the filament or the glass envelope of the bulb. This helps to extend the life of the bulb by preventing the filament from degrading. Additionally, argon helps to reduce the rate of evaporation of the filament, leading to a longer-lasting bulb.
Why are light bulbs filled with argon and not air?
Light bulbs are filled with argon instead of air because argon is an inert gas that helps prevent the filament from oxidizing and burning out quickly. Air contains oxygen, which can cause the filament to degrade faster due to oxidation. Argon creates a more stable environment inside the bulb, prolonging the life of the filament.
What causes filament to burn out?
Filament burns out due to the high temperature causing it to evaporate, leading to weakening and breakage. Factors such as excessive voltage, frequent on-off cycles, and poor ventilation can also contribute to filament burnout.
Which gas in the air is needed for a filament to burn?
Oxygen is the gas in the air that is needed for a filament to burn. Oxygen supports combustion by reacting with the material in the filament, allowing it to produce light and heat.

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 does gas burn in the air to form?
Gas burns in the air to form carbon dioxide (CO2) and water (H2O).
Why the central blue cone in the blue flame is unburnt gas?
because no air enters it. The air burns 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.

What is the poisonous gas formed when methane burns in a limited supply of air?
Carbon monoxide is the poisonous gas formed when methane burns in a limited supply of air.
If a natural gas line is ignited does it burn back to the source of the gas?
it only burns in the air
Which gas in the air is used when icing sugar burns?
Oxygen.
What product is formed when hydrogen burns the air?
When hydrogen burns in air, it forms water (H2O). This is a chemical reaction in which hydrogen gas (H2) reacts with oxygen gas (O2) to produce water vapor.
