oxygen must be present in order for fuel to burn.
That depends on the fuel. Natural gas, methane, needs 2 molecules of oxygen, but gasoline, octane, needs 17 molecules of oxygen.
In order for fire to burn, there is someting called the fire tetrahedron. The things needed for fire to burn are as listed: Heat, Oxygen, Fuel(of any sort), and a Chmeical Reaction with all of the above. I learned this from the multiple firefighting classes i have taken.
To burn a fuel, the other two things needed are oxygen and heat. Heat could come from a flame to start the fire (once the fire is started it continues to produce enough heat unless it runs out of fuel or oxygen, or is put out), or it could come from a spark.
No, fire does not need carbon to burn. Fire requires three elements to ignite and sustain: heat, fuel, and oxygen. Carbon is a common fuel source for fires, but other materials like wood, paper, and gas can also serve as fuel for combustion.
The rocket carries its own supply of oxygen with which to burn the fuel.
Oxygen is necessary to burn a fuel. In the presence of oxygen, the fuel undergoes a chemical reaction known as combustion, releasing heat and light energy.
HEAT
For a flame to burn it needs fuel, oxygen, and heat.
Lungs provide the body with oxygen. Oxygen is not exactly a fuel, but oxygen is necessary in order to burn fuel. Fuel for the body comes in the form of food, and oxygen is necessary to metabolize the food.
Technically hydrogen and helium do not need oxygen to burn, they burn by themselves, otherwise the object that needs burning must have oxygen as a supplimental fuel source.
No. They just take oxygen from the air.
All fuels that 'burn' require air or an oxygen source for combustion. Therefore,fossil fuel also burn in the air.
Oxygen and heat to get things going
fire needs oxygen to burn, because fire is a chemical reaction that needs oxygen. the fire triangle is what fire needs to burn and is this- heat, fuel, and oxygen.
oxygen is needed for fuel to burn
Approximately 16 pounds of oxygen are required to burn 1 pound of 2 fuel oil. This is based on the stoichiometric ratio of oxygen to fuel oil for complete combustion.
