As a chemistry expert with a background in material science, I often deal with the properties of various gases and their interactions with different substances. Let's delve into the nature of oxygen and its role in combustion.
Oxygen, with the chemical symbol O2, is a diatomic molecule and the second most abundant element in the Earth's crust, after silicon. It is a vital component of the air we breathe, making up approximately 21% of the Earth's atmosphere. Oxygen is a reactive gas, and its reactivity is what makes it essential for life as we know it, as it is a key component in the process of cellular respiration.
The question of whether pure oxygen is highly flammable is a nuanced one. To understand this, we must first define what we mean by "flammable." A substance is considered flammable if it can ignite easily and burn rapidly.
Oxygen itself is not flammable; it does not burn. However, it is an oxidizer, which means it can support and enhance the combustion of other materials.
The combustion process involves a chemical reaction between a fuel and an oxidizer, which releases energy in the form of heat and light. The fuel can be a solid, liquid, or gas, and the oxidizer is typically oxygen. When oxygen is present, it reacts with the fuel, accepting electrons and forming oxides. This reaction is exothermic, meaning it releases energy.
In a pure oxygen environment, the combustion process can be more intense than in air. This is because the concentration of oxygen is higher, which means there is more oxygen available to react with the fuel. This can lead to a more rapid and potentially more violent combustion process. For example, materials that might not burn in normal air can ignite and burn in a pure oxygen atmosphere.
It is also important to note that the purity of oxygen can affect its reactivity. Pure oxygen, as found in oxygen tanks or produced by an oxygen concentrator, is more reactive than the oxygen found in the air, which is diluted with other gases like nitrogen. Nitrogen acts as a diluent, reducing the concentration of oxygen and thus its reactivity.
In industrial and medical settings, the use of pure oxygen requires careful handling and safety precautions. High concentrations of oxygen can pose a fire risk, especially in the presence of flammable materials. For instance, in a welding process, pure oxygen is used to create a high-temperature flame for cutting or joining metals.
In summary, while pure oxygen is not flammable, it is a potent oxidizer that can significantly influence the combustion of other materials. Its reactivity and the intensity of combustion can be enhanced in a pure oxygen environment compared to air. Understanding and managing these properties are crucial for safe and effective use in various applications.

After nitrogen, the most abundant gas in our air is oxygen. Here's where it gets complicated: Oxygen is also not flammable, but it is a high-energy gas that very readily oxidizes other materials. For something to burn, the reaction requires a fuel (the thing that burns) and an oxidizer like oxygen.
