Worked practice questions
Which noble gas is used as a shielding gas in welding?
- Neon
- Helium
- Radon
- Argon
Show answer and solution
Correct answer: D. Argon
Argon is inert and denser than air, so it blankets the weld from oxygen.
Which noble gas is used to provide buoyancy in blimps and balloons?
- Helium
- Argon
- Xenon
- Krypton
Show answer and solution
Correct answer: A. Helium
Helium is very light and non-flammable, so it lifts balloons safely.
