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.
Gasoline can ignite at temperatures as low as -45 degrees Fahrenheit (-43 degrees Celsius).
Chemicals that can cause gasoline to ignite include heat, sparks, and flames. Gasoline is highly flammable and can ignite easily when exposed to these ignition sources. It is important to handle gasoline with caution and avoid situations where it may come into contact with these chemicals.
Because a spark could potentially ignite gasoline, and cause a catastrophic explosion.
No, gasoline requires oxygen to ignite and burn. Without oxygen, gasoline cannot undergo the combustion reaction necessary for an explosion.
It is harder to ignite higher octane gasoline - the octane rating expresses the compound's resistance to pre-ignition (often called "ping") Low octane fuels tend to 'ping' more than high octane fuels because they ignite more easily.
Yes, gasoline is volatile because it can easily evaporate into the air at normal temperatures. This volatility is what makes gasoline highly flammable and able to ignite easily.
It is extremely dangerous to smoke near gasoline as it is highly flammable. Even a small spark from a cigarette can ignite gasoline fumes which can result in a fire or explosion. It is best to avoid smoking altogether when handling gasoline.
Yes. All the gasoline needs is a source of ignition like a wayward spark from a spark plug wire.
Pour 5 gallons of gasoline in engine bay. Strike match and ignite gasoline. Presto! All fixed!
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.
Kerosene burns slower than gasoline because it has a higher flash point and is less volatile. This means that kerosene requires more time and heat to ignite and burn compared to gasoline.
diesel vapors due not ignite like gasoline does. Also diesel has a totally different smell.
