Complete step-by-step answer: Argon is a commonly used gas, used to fill incandescent light bulbs. It increases the bulb life by preventing the tungsten filament from deteriorating too quickly. Other gases such as helium, neon nitrogen and krypton are also used in lightning.
Which of the following gases are filled in electric bulbs 2 points helium and neon argon and neon argon and hydrogen argon and nitrogen?
The correct answer is Nitrogen. Helium, neon, argon krypton, and argon are the gases used in light bulbs.
Which of the following are filled in electric bulbs?
Electric bulbs are filled with Argon. Argon is an inert gas. Inert gases have low reactivity.
Which of the following gases is filled in electric bulbs argon and?
The filament in an electric bulb is made using tungsten which would burn quickly when it comes in contact with the oxygen in the air. This is the reason why unreactive gases such as argon and nitrogen are used for filling an electric bulb. These gases are chemically interactive.
Which two gases are filled in bulb?
Two gases which are filled in filament type electric bulb are argon and neon.
Why gases are filled in bulb?
The main reason that bulbs are filled with an inert gas is to reduce evaporation of the filament and prevent its oxidation. The most popularly used filling in electric bulbs is a mixture of Argon and Nitrogen.
Why are electric bulbs filled with Argon and Nitrogen?
The filament in an electric bulb is made using tungsten which would burn quickly when it comes in contact with the oxygen in the air. … Hence, bulbs are filled with chemically inactive Nitrogen or Argon gas in order to prevent the oxidation of tungsten filament used in the bulb.
What is the filament of an electric bulb made of?
Now, filaments of electric bulbs are made up of tungsten. To understand why, let us look at some properties of tungsten that contribute to its versatility. As a metal, Tungsten is a good electrical conductor. It is also a good thermal conductor.
Which metal is used to make the filament of an electric bulb?
Tungsten is used in filaments of incandescent light bulbs.
