Oxygen is one of three things that must be present for a fire to exist. The three things are:
- an oxidizer (oxygen is the most common one),
- fuel (something to burn - that is to combine very rapidly in a chemical reaction with oxygen), and
- a source of ignition (a spark, heat, etc.)
Oxygen is necessary for fire to burn. When oxygen is present in sufficient amounts, it allows a fire to grow and spread by creating a chemical reaction that releases energy in the form of heat and light. If oxygen is restricted or depleted, the fire will be deprived of the necessary element to sustain combustion, causing it to extinguish.

What is an oxygen fed-fire?
An oxygen-fed fire is a fire that is fueled by an increased supply of oxygen, resulting in a more intense and faster-burning fire. It can be more difficult to control and extinguish due to the higher oxygen levels supporting combustion.
What is a Source of oxygen for a fire?
the air
What happens when you remove oxygen from a wood fire?
When you remove oxygen from a wood fire, the combustion process stops because oxygen is necessary for wood to burn. The fire will gradually extinguish as it depletes the available oxygen supply.
What percentage of oxygen is needed for a fire?
A fire needs approximately 16% oxygen in the air to sustain combustion. This is known as the oxygen concentration level for combustion. If the oxygen level drops below this threshold, the fire will be deprived of oxygen and will be extinguished.
How can water remove the oxygen in a fire?
Water removes oxygen from a fire by suffocating it. When water is applied to a fire, it turns into steam, which displaces the oxygen around the fire. This reduction in oxygen levels prevents the fire from continuing to burn.
What effects does oxygen have on fire?
Oxygen keeps the fire going. In some cases, it can make the fire larger, depending on the amount of oxygen around the fire.
What liquid affects fire the most?
A chemical fire would be affected by the amount of hydrogen in the mixture; in the open, oxygen effects the fire the most.
How does oxygen distribute fire?
Oxygen does not distribute fire. Fire is a chemical reaction between oxygen and some flammable substance. Fire cannot burn without oxygen, and the more oxygen there is, the hotter and faster a fire will burn. More oxygen also makes it easier for materials to ignite.
What are the useful effects of chemical changes?
Chemical changes are very important!! See an example: when Oxygen combines with Hydrogen, it forms water. Oxygen helps combustion and hydrogen is combustible i.e. both help fire but water helps keep away that fire....
What is an oxygen fed-fire?
An oxygen-fed fire is a fire that is fueled by an increased supply of oxygen, resulting in a more intense and faster-burning fire. It can be more difficult to control and extinguish due to the higher oxygen levels supporting combustion.
Why charcoal burns slowly when left undisturbed?
Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen. Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen.
What is a Source of oxygen for a fire?
the air
What happens when you remove fuel and oxygen from fire?
If you remove fuel, oxygen, or both from a fire, the fire goes out.
What does oxygen do for fire?
Fire is the release of heat and light during the very rapid combination of oxygen with another substance that we call the fuel of the fire. Although there are other oxidizers that can perform a similar function, in most cases in everyday life you cannot have a fire without a source of oxygen.
Is fire under the ocean?
Fire requires oxygen. There is no free oxygen in the ocean. Therefore there can be no fire at the bottom of the ocean.
Why cant you set a fire to the Moon's surface?
there is no oxygen on the moon, therefore, a fire could not start because in the fire triangle, (the materials needed to start a fire) the fire needs oxygen, which the moon does not have, fuel, and heat.
What happens when you remove oxygen from a wood fire?
When you remove oxygen from a wood fire, the combustion process stops because oxygen is necessary for wood to burn. The fire will gradually extinguish as it depletes the available oxygen supply.
