How much oxygen does a fire need to ignite?
Fires require oxygen to ignite and sustain combustion. In general, fires need around 16% to 17% of oxygen in the air to burn. This oxygen level is typically found in the Earth's atmosphere.
How much oxygen can be present before hydrogen ignites?
Hydrogen can ignite when the concentration of oxygen in the air is between 4% and 75%. Below 4%, there is not enough oxygen for ignition, and above 75%, the mixture becomes too rich to ignite.
What is more flammable than gasoline?
The flammablilty of liquids is measured by flash point this is the minimum temperature in which a spark will ignite it. Gasoline which is a mixture has a flash point of around 0 degrees C. One of the most flammable liquids, Diethyl ether has a flash point of -45 degrees so is much more flammable than gasoline.
How much oxygen is needed to sustain combustion?
Oxygen is required to sustain combustion as it is the oxidizer that allows for the chemical reaction with the fuel. The exact amount of oxygen needed depends on the type of fuel being burned, as different fuels have different oxygen requirements for combustion. In general, combustion requires a sufficient supply of oxygen to ensure complete oxidation of the fuel.
How much oxygen in needed to sustian fire?
In general, fire requires oxygen levels of at least 16% to sustain combustion. Below this threshold, a fire will not be able to burn efficiently, and may eventually extinguish due to lack of oxygen. However, the exact amount of oxygen needed can vary depending on the type of fuel and the conditions present.
Why does gasoline ignite?
Gasoline ignites because gasoline is flammable. (simple answer) A more detailed answer would be. Gasoline produces flammable vapors at a much lower temperature than almost any other 'common' chemical. It is the vapors that ignite rather than the chemical itself. Also Gasoline vapors are heavier than air. Any 'Flammable' chemical will ignite in the presence of an open flame or spark if there are sufficient fumes.

Why the cars which run on petrol cant be run with diesel?
Petrol engines use a spark plug to ignite the gasoline. Diesels on the other hand use compression to ignite the fuel. Diesel engines have a very high compression ratio that causes the fuel to ignite under pressure. Gasoline engine do not run near the compression as a diesel. Put diesel in a gasoline engine and it simply will not run. Reason being is that diesel fuel has a much higher flash point. Gasoline contains 4 to 12 carbon atoms, diesel has 10 to 20 carbon atoms and is much heavier than gasoline.
What does engine running rich or lean mean?
An engine runs by the combustion of a mixture of oxygen and gasoline. If this mix has too much oxygen, it is said to run lean. When the mixture has too much gasoline in relation to oxygen, it is running rich.
Can you ignite Neptune?
No, you can't ignite Neptune. While much of Neptune's atmosphere is hydrogen, there is no oxygen there to support combustion.
How much gasoline does a Honda rubicon 500 need and how much fuel stabalizer is needed?
4 gallons

How much oxygen is needed by a human body?
A lot
How does diesel fuel ignite in the engine?
The engine's pistons compress the fuel (an air and diesel oil mixture) in the cylinders and the heat generated by that compression causes the fuel to ignite.A longer answerDiesel engines ignite their fuel solely by means of compression: whilst spark plugs are used to ignite the gasoline fuel and air mixture in gasoline engines, in diesel engines the diesel oil and air mixture is compressed to a very much higher degree, which causes a lot of heat. The resulting very high temperature causes the fuel to self-ignite.
How much oxygen is needed to sustain the burning process?
15%
Why do you get fewer miles per gallon from a gallon of ethanol than from a gallon of gasoline?
Gasoline enriched with ethanol contains more oxygen - so it burns cleaner and much faster than regular gasoline. Which means it increase the power of your car.
