Gasoline is the most widely used liquid fuel. Gasoline, as it is known in United States and Canada, or petrol virtually everywhere else, is made of hydrocarbon molecules (compounds that contain hydrogen and carbon only) forming aliphatic compounds, or chains of carbons with hydrogen atoms attached.
Is petrol a pure liquid?
Answer: A homogeneous mixture consists of only one phase. … (ii) Petrol, kerosene oil, diesel oil are homogeneous mixtures of various liquid hydrocarbons in only one phase i.e. liquid. Same way, sugar dissolved in water gives a homogeneous mixture having only the liquid phase.
Is petrol a gas or liquid?
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.
Are diesels better than petrol?
Diesels deliver more power at lower engine revs than their petrol equivalent. This makes diesels feel more suited to longer motorway trips because they’re not working as hard as petrol engines to produce the same performance. This also helps to make diesel cars better suited for towing.
Why is petrol called gasoline?
In a lot of organic chemistry, -ene or -ine is used (think benzene/benzine), and so the part of the petroleum distilled-off and used in motor vehicles was the part of highest volatility, and in time was dubbed gasoline.
What are the advantages of liquid fuel?
Advantages of liquid fuels :
They possess higher calorific value per unit mass than solid fuels. They burn without forming dust, ash, clinkers etc. Their firing is easier and also fire can be extinguished easily by stopping the liquid fuel supply. They are easy to transport through pipes.
How much petrol is safe in a diesel car?
As a safe amount some car manufacturers will say none though the industry generally accepts 7.5% or less of petrol in diesel is safe. When you work it out for your tank capacity you will soon realise it’s not a lot of the wrong fuel before it’s too much.
Is diesel heavier than petrol?
The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).
What’s more viscous petrol or diesel?
Diesel is refined at a higher temperature than petrol and has a certain viscosity according to the different surrounding temperatures (unlike petrol). … The fuels in the Diesel range are known as middle distillates, whereas Petrol, is known as coming from the Petroleum spirit range.
