Question: 1 / 400

Is oxygen flammable?

True

False

Oxygen itself is not flammable, which is why the answer is considered correct. It is essential to clarify that while oxygen supports combustion, it does not ignite on its own. Flammability refers to the ability of a substance to catch fire and burn, and oxygen acts as an oxidizer rather than a fuel source.

In many practical situations, such as in the presence of a fuel source and an ignition source, oxygen can facilitate or enhance the burning process. However, it is not classified as a flammable substance because it does not produce combustion independently.

Other options imply conditions under which oxygen might burn or be involved in combustion, but it’s important to understand that while oxygen is crucial for maintaining flames, it itself does not catch fire, making it fundamentally non-flammable.
