Q:

Why is argon gas used along with tungsten wire in an electric bulb?

A) To increase the life of the bulb B) To reduce the consumption of electricity
C) To make the emitted light colored D) To reduce the cost of the bulb
 
Answer & Explanation Answer: A) To increase the life of the bulb

Explanation:

Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.

The use of argon in light bulbs prevents the evaporation of the tungsten filaments, which results in increased light bulb life.

Argon is also used to create an inert atmosphere for growing semiconductor crystals, arc welding and for processes that need protection from other kinds of atmospheric gases.
