C1a MAKING CRUDE OIL

HideShow resource information
what are fossil fuels ?
crude oil, coal , gas
1 of 15
what is used to form coal?
dead plant material
2 of 15
what is used to form crude oil ?
dead marine organisms
3 of 15
why are fossil fuels a finite resource ?
they are no longer being made and they they extremely long to be made.
4 of 15
why are fossil fuels a non-renewable resource ?
they are used up faster than made.
5 of 15
what is crude oil of a mixture of ?
many hydrocarbons
6 of 15
what are the environmental problems associated with transporting crude oil ?
oil slicks can travel across sea spreading damage, beaches and wildlife are harmed when they're coated with oil.
7 of 15
how are birds affected by oil spills ?
it damaged the birds feathers and causes birds to die
8 of 15
what is distillation ?
a process that separates a pure liquid from a mixture of liquids.
9 of 15
what is distillation commonly used for ?
its commonly used to separate ethanol from water
10 of 15
what does the cracking process do ?
converts large alkane molecules into smaller alkane and alkene molecules. it also makes useful alkene molecules that can be used to make polymers
11 of 15
what are the political problems associated with exploitation of crude oil ?
UK is dependant on oil and gas from unstable countries, there are future supply issues.
12 of 15
what are the problems associated with the finite nature of crude oil ?
they will be used up in the future, finding replacement, conflict between making petrochemicals and fuels
13 of 15
during boiling of crude oil which bonds are broken ?
the intermolecular forces
14 of 15
why crude oil can be separated by fractional distillation?
The smallest molecules contained in the crude oil have lower boiling points and so move to the top of the tower. This is because the forces between these molecules are weak, so little energy is required to vaporise them. Larger molecules will remain
