Question

Oxygen is a non combustible gas
a.) True
b.) False

Answer 1

Hint: Before answering this question, we should have an idea about combustion and combustible substances. Combustion, is a high- temperature exothermic redox chemical reaction, between a fuel and an oxidant. On the other hand, combustible substances are defined as those substances, which burn in air to produce light and heat.
Complete step-by-step answer:
Before we conclude the answer, we need to examine the participation of oxygen in the process of combustion.
Oxygen does not burn. It is not flammable, but it is an oxidizer. Oxygen needs fire, so it is dangerous to use around something that is burning, because it will help the fire to burn more quickly.
Therefore, we can say that oxygen is a non-combustible gas. It only supports the process of combustion.
So the answer to the question whether oxygen is a non combustible gas or not is true.

So the correct option is Option A.

Note: Some uses of oxygen, as a non- combustible gas are:
Oxygen therapy is a treatment that delivers oxygen gas for us to breathe.
Oxygen is used with fuel gases in gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening, and flame straightening.
In metallurgy, oxygen too finds its use. For instance, oxygen is used in the production of steel. It is used in a blast furnace to turn carbon into carbon dioxide, which reduces the iron oxides to pure iron.
Oxygen gas low thermal energy and electrical conductivity. But it has high electronegativity and ionization energy.
