Yeah they are!
Calor gas, petrol, naptha, paraffin, diesel, fuel oil, lubricating oil and bitumen all come out of a fractionating column
kerosine
which one out of naptha diesel bitumen and petrol is the easiest to turn in to gas in order best to worse.
It is when you break large hydrocarbons/alkanes, into smaller more useful alkanes/alkenes. For example a large hydrocarbon in crude oil is Bitumen. By passing this substance over a hot catalyst, you can break it down into smaller hydrocarbons such as Petrol or Diesel
Petrol composition ranges from C5-C12 while that of Diesel average composition is C12H23, ranging from approx. C10H20 to C15H28. So it shows that Diesel consists of heaveir hydrocarbons than Petrol.
fossil fuels
I am pretty sure the answer is hydrocarbons.
Bitumen is black.
Mixture of naturally occurring hydrocarbons that is refined into diesel, gasoline ------------------------- Crude petrol is petrol as extracted, without any treatment.
bitumen, fuel oil, lubricating oil, diesel, kerosene, naphtha, petrol, refinery gas
Diesel and petrol (gasoline) are flammable fossil fuels containing hydrocarbons that we get when plants and animals get buried in the soil and decay over many years. It eventually forms crude oil which is refined into petrol or diesel.
because bitumen has higher molar mass than petrol (more molecules than petrol), bitumen needs more energy to vaporize its molecules than petrol
