Is Nitrous oxide explosive and flammable?

  1. Yes

  2. No

  3. Only Explosive

  4. Only Flammable

The correct answer is: No

Nitrous oxide, commonly known as laughing gas, is not explosive nor flammable. Although it supports combustion, it is only mildly oxidizing and requires a source of fuel to ignite. This means that it can enhance or accelerate a fire but it cannot explode on its own. Therefore, options A and C are incorrect as they suggest that nitrous oxide is both explosive and flammable. Option D is also incorrect as it implies that nitrous oxide is only flammable.
