Is Helium flammable?

Is Helium flammable?

• A. True
• B. False
• C. Depends on the concentration
• D. Only in high temperatures

Answer: (B)

Helium is classified as a noble gas, which means it is chemically inert and does not readily react with other elements or compounds. This unique property makes helium non-flammable; it will not ignite or support combustion in any concentration. Unlike gases such as hydrogen or methane, which can catch fire and sustain flames, helium remains stable and does not participate in chemical reactions that would lead to burning. The other options suggest scenarios where helium might be flammable or dependent on certain conditions, but these do not apply. Helium’s lack of reactivity ensures that it will not catch fire or contribute to combustion, regardless of the temperatures or concentrations involved. Therefore, the assertion that helium is non-flammable is accurate and highlights its safety in various applications.
