Which gas is used in electric bulbs to prevent oxidation of the filament?

Last Updated:

Built around the concept in “Which gas is used in electric bulbs to prevent oxidation of the filament?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Argon.

ANitrogen
BArgon
CCarbon dioxide
DOxygen
Correct Answer: ArgonYour Answer: B

Explanation

The defining scientific property identifies Argon. Argon is an inert gas used in bulbs to protect the tungsten filament. The alternatives Nitrogen, Carbon dioxide and Oxygen are legitimate scientific terms, but each belongs to a different function, property, material or context.

Important Notes

  • Verified answer: Argon; option B, zero-based index
  • Core scientific fact: Argon is an inert gas used in bulbs to protect the tungsten filament.
  • Distractors Nitrogen, Carbon dioxide, Oxygen represent different scientific associations.
  • Revision pair: “Which gas is used in electric bulbs to prevent oxidation of the filament? — Argon”.

What is General Science and which topics are important for competitive exams?

General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.

What are Newton's Laws of Motion?

Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
