the higher self ignition temperature of the petrol is due to the low density than the diesel.
as
density = pressure / (R* temperature)
R= universal gas constant.
ex. hydrogen (gas) has density = .082 at 300 k
while kerosene has =810
(both are in kg/m^3)
and auto ignition temperatures are
hydrogen =500
kreosene=295
similarly , petrol-density=737
diesel has=820 to 950 .
What else can I help you with?
Will a fuel with a higher boiling point be a better fuel than one with a lower boiling point?
A low boiling point one would be better as it will use less heat and release Co2 into the air. --------------------------------------------------------------------------------------------------------- Twitter @TrolPie
What has a higher boiling point than jet fuel?
water
What are the differences between butane and methane in terms of their chemical properties and uses?
Butane and methane are both hydrocarbons, but they differ in their chemical properties and uses. Butane has a higher boiling point and is commonly used as a fuel for lighters and camping stoves. Methane has a lower boiling point and is mainly used as a natural gas for heating and cooking.
Why might propan 1 ol not be used as a fuel?
Propan-1-ol (1-propanol) has a high boiling point and is less volatile compared to other fuel options like gasoline or diesel. This makes it less suitable for use as a fuel because it would not vaporize easily for combustion in engines. Additionally, propan-1-ol is more commonly used in industrial applications and as a solvent rather than as a fuel.
Is it true that boiling point of a liquid remains constant in all altitudes?
No. The higher the altitude the more difficult, and fuel expensive, to boil water.

Why does gasoline have a lower boiling point than fuel oil?
The size of molecules determine how well the molecules hold together/attract each other. Gasoline has a molecular mass of around 114 units whereas fuel oil is a bigger molecule by about a factor of 3 or more. This means boiling point is higher for fuel oil because you have to break apart the molecules to get them to boil. (Boiling is vaporizing the substance.) This same chemical property means that gasoline is less viscous more volatile than fuel oil.
What properties are of significance on the ignition of a liquid fuel released in spray form?
boiling point

What is the top of an oil fractionating column is?
The top of an oil fractionating column is where the lighter hydrocarbon fractions, such as gases and light liquids, are collected and removed from the column. This process separates the different components of crude oil based on their boiling points.
What is the relationship between flash point and initial boiling point in diesel?
The flash point of diesel fuel is the lowest temperature at which its vapors can ignite in air, while the initial boiling point is the temperature at which the first portion of the liquid begins to evaporate. Generally, diesel has a flash point that is higher than its initial boiling point, indicating that it requires a higher temperature to ignite compared to the temperature at which it starts to vaporize. This relationship is crucial for safety and storage considerations, as it affects handling and potential fire hazards. In essence, the flash point helps define the flammability risk associated with the fuel under different temperature conditions.
Is it true that boiling point of a liquid remains constant in all altitudes?
No. The higher the altitude the more difficult, and fuel expensive, to boil water.
How to separate petrolium into fractions?
fractional distillation. you use the boiling point to separate petroleum into its different compounds. the order is asphalt, lubricating oil, jet fuel and diesel fuel, kerosene, and gasoline.
