The flash point is an indication of how easy a chemical may burn. Materials with higher flash points are less flammable or hazardous than chemicals with lower flash points.
Fuels and their flash points at atmospheric pressure are indicated in the table below:FuelFlash Point

The flammable (explosive) range is the range of a gas or vapor concentration that will burn or explode if an ignition source is introduced. Limiting concentrations are commonly called the lower explosive or flammable limit(LEL/LFL) and the upper explosive or flammable limit (UEL/UFL).
Below the explosive or flammable limit the mixture is too lean to burn. Above the upper explosive or flammable limit the mixture is too rich to burn. The Auto-Ignition Temperature is not the same as Flash Point - The Flash Point indicates how easy a chemical may burn.

Which burns slower kerosene or gasoline?
Kerosene
Does temperature make petrol evaporate?
In a petrol engine, the petrol is evaporated before it is burnt, this means it burns better, increasing engine efficiency.
Why is petrol regarded as a better fuel than kerosene?
In petrol, the combustion of hydrocarbons present is complete and they burn with blue flame. However, in kerosene, the combustion is not complete. It burns with smoky flame accompanied by the release of unburnt carbon atoms. Therefore, petrol is regarded as a better fuel than kerosene.
How safe is it for engine life if converted from Petrol to CNG?
Gasoline (petrol) engines can be converted to run quite well on Compressed Natural Gas. It burns much cleaner than gasoline, with longer engine life,
Why does gasoline burn faster than diesel?
It is more volatile. It vaporizes easier and therefor burns faster.
Why does kerosene oil catch fire faster than wood?
This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
Why does kerosene oil burns with a flame whereas coal does not?
This is because coal does not have complete combustion whereas candle or kerosene burns completely
How do you tell petrol from diesel in a can?
Petrol is and bit more vicous and that diesel is a lot darker than petrol. Petrol burns quicker when set alight, however diesel burns more brightly!
Which will not form water and carbon dioxide when it burns?
kerosene+
How do kerosene pollute land?
kerosene burns and pollutes the world killing everyone! within seconds
Are some brands of petrol better?
Yes. Definitely. Better refinement, better batches of crude, better detergents to clean your engine as it burns, also burns cleaner and more complete. Shell gasoline is very good, but since you called it petrol, I'm assuming you may be in the U.K. ? B.P. is of a very good quality, as well.
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.
