because Oxygen is a required chemical for the thermal/chemical reaction that is fire.
If you place a large glass container over the flame and seal all exits, you will see the flame slowly die out.

∙ 14y agoheat breaks long cellulose molecules down into shorter molecules that can react with oxygen in a process called 'pyrolysis.' heat is required to initiate pyrolysis in fuel before the fuel will burn. smaller pieces of tinder or kindling will heat more easily than larger pieces. since heat rises, allow the flame to rise up the match or tinder to heat additional fuel. Heat can be suppressed with dirt or water, by spreading the fuel apart, or by adding green or wet wood which requires more heat to dry it.

∙ 11y agoIf it didn't have heat then it wouldn't be able to burn something burn is something getting really hot hot = heat so yeah

∙ 15y agoFuel is one of the three essential elements that must be present, the other two being heat and oxygen, remove any one of these elements and the fire will go out.

As they said, it's like humans need oxygen to breath, fire need's oxygen to thrive.

What are the 3 ingredients of fire?
For fire you need three main ingredients. First you need a fuel, this fuel can be anything that burns like wood for example. Second you need oxygen, without oxygen a fire cannot burn. Finally you need heat, even though fires give off heat you still need it to start a fire. If you remove any one of these three ingredients then the fire will die.
What is needed for something to burn?
Fire need a fuel, so wood or leaves and of course it needs Oxygen (O2)! That's that. A fire needs three things, feul, oxygen and heat, remove any one and the fire will die.
Four elements that must be present for fire to exist include?
The fire tetrahedron consists of oxygen, heat, fuel and a chemical reaction.
How does a fire triangle work?
All 3 things around the triangle you need to create and sustain fire - heat-fuel-oxygen. If you take any of them out you can not produce or sustain a fire.
What elements does not need to be present for fire to exist oxgen carbon monoxide fuel or combusible material or heat?
Carbon monoxide is NOT required.
What do you need to start a fire?
You need oxygen, heat, and fuel.

Why do you need car engine to heat heat up quickly?
it can cause to fire and
What ingredients do you need for a fire?
Fuel, oxygen and heat.
What do you need to create fire?
To create a fire you need a fuel source of some kind, oxygen (O2), and a heat source.
What does fire need to stay lit?
heat oxtgen and fuel
What do we need to make fire?
Fuel, oxygen, & an energy (heat) source.
How much heat does fire have?
Fire, all fire, every fire consists of 3 things: Heat, Fuel & Oxygen. When all 3 are together in the right mix you have fire, if one or more elements is not sufficient then you cannot have fire. You therefore need as much heat as necessary along with the fuel & oxygen to maintain the fire. The specific answer is that the balance of the 3 must be correct. Quantifying that, however, is a different matter.

Does a fire need fuel oxygen and heat to burn?
Yes it does. If either fuel oxygen or heat were not sufficient or absent, fire would not be able to be sustained or ignited. :)
ABC fire extinguishers extinguish fires by cooling it down.?
True (You Need Heat, Fuel, and Combustible) ABC Extinguishers Cool down the fire breaking the fire triangle by removing the heat.
What does a fire need to stay burning?
Oxygen, fuel, heat. (remove any one of these three and your fire will go out)
