What process involves the creation of a new compound from the combination of oxygen and another substance?

The process that involves the creation of a new compound from the combination of oxygen and another substance is known as oxidation. During oxidation, a substance reacts with oxygen, often resulting in the formation of oxides. This is a key concept in various chemical reactions, including combustion, where a fuel reacts with oxygen to produce heat and light as well as new compounds, such as carbon dioxide and water.

In the context of fire science, understanding oxidation is crucial as it relates directly to how fires ignite and sustain themselves. The introduction of oxygen to a combustible material leads to its oxidation, releasing energy in the form of heat and light, which is the underlying principle of combustion reactions.

While combustion does involve oxygen and results in the creation of new compounds, it is specific to reactions that produce heat and light, whereas oxidation is a broader term encompassing any reaction involving oxygen. Therefore, recognizing oxidation as the foundational process helps in understanding various related phenomena in fire dynamics and chemistry.
