Flash point refers to the lowest temperature at which a fuel will vaporize and ignite. Flash point and volatility vary inversely. The lower the flash point, the higher the volatility. Gasoline has a higher volatility than diesel.
Which is more volatile diesel or petrol?
In comparison to diesel fuel, gasoline is lighter, less dense, more flammable and more volatile. … Diesel fuel is heavier, denser, less flammable and less volatile. So to detonate it, it has to be compressed in a cylinder to a very high pressure and temperature, at which point it detonates without a spark.
What is the most volatile fuel?
Gasoline is highly volatile due to its low flash point and easily vaporizes when exposed to air.
Is petrol highly volatile?
Gasoline, also spelled gasolene, also called gas or petrol, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats.
Is diesel less volatile than gas?
Diesel fuel, also called diesel oil, combustible liquid used as fuel for diesel engines, ordinarily obtained from fractions of crude oil that are less volatile than the fractions used in gasoline.
Are diesels better than petrol?
Diesels deliver more power at lower engine revs than their petrol equivalent. … This also helps to make diesel cars better suited for towing. Better fuel economy. Like for like, diesel cars give you better mpg than petrol ones.
Why is petrol volatile in nature?
➡ Petrol Is Most Volatile . ➡In comparison, waterevaporates more slowly thanpetrol. ➡That’s because watermolecules have hydrogen bonding which is a strong intermolecular attraction. … ➡Some hydrocarbons are more volatile (evaporate morequickly) than petrol.
Which material is most volatile?
In the table, boron is the least volatile and hydrogen the most volatile substance.
Is low fuel volatility good?
Low volatility gasoline helps reduce hydrocarbon emissions from evaporated fuel. “RVP” is the abbreviation for “Reid Vapor Pressure”, a method used to measure fuel vapor pressure. This requirement is needed to protect our environment and improve air quality.
Which is more volatile petrol or kerosene?
Kerosene is less volatile than gasoline. Its flash point (the temperature at which it will generate a flammable vapour near its surface) is 38 °C (100 °F) or higher, whereas that of gasoline is as low as −40 °C (−40 °F). This property makes kerosene a relatively safe fuel to store and handle.
