A resource that is no longer being made, or are being made very slowly.
1 of 16
What is a non-renewable resource?
A resource that is being used up faster than it is being created/formed.
2 of 16
What are two specific difficulties associated with the finite nature of crude oil?
All of the readily extractable resources will be used up in the future and trouble finding replacements.
3 of 16
What is a hydrocarbon?
Something containing only hydrogen and carbon atoms.
4 of 16
Name the oils separated in the fractional distillation tower? starting with the oil with the lowest boiling point.
LPG, Petrol, Paraffin, Diesel, Heating oil, Fuel oils and Bitumen
5 of 16
Does Bitumen have a high or a low boiling point?
Oil that doesn't boil sinks as a thick liquid to the bottom. This is bitumen. Bitumen has a very high boiling point. It exists at the bottom of the column.
6 of 16
Where do fractions with low boiling points go?
Other fractions containing mixtures of hydrocarbons with similar boiling points, boil and their gases rise up the column. The column is cooler at the top. Fractions with lower boiling points exit towards the top of the column.
7 of 16
Why can crude oil be seperated?
Because the hydrocarbons in different fractions have different sized molecules.
8 of 16
What is the name of the forces between the molecules that are broken during boiling?
Intermolecular forces.
9 of 16
The molecules of the liquid seperate from each other as......................
Molecules of gas.
10 of 16
Why are fractions with high boiling points harder to break apart?
Large molecules, such as those of bitumen and heavy oil, have strong forces of attraction. A lot of energy is needed to break the forces between the molecules. These fractions have high boiling points.
11 of 16
Why are fractions with low boiling points easier to break apart?
Smaller molecules, such as petrol, have weak attractive forces between them and are easily separated. Less energy is needed to break the forces between the molecules. These fractions have low boiling points.

How can the transport of crude oils harm wildlife?
Oil slicks can damage birds' feathers and cause their deaths. Clean up operations use detergents that can damage wildlife.
13 of 16
What political problems can be created from the extraction of crude oil?
Oil producing nations can set high prices and cause problems for the future supply of non-oil producing nations.
14 of 16
What is cracking?
Cracking is a process that turns large alkane molecules into smaller alkane and alkene molecules. An alkene molecule has a double bond, which makes it useful for making polymers.
15 of 16
How can cracking help oil manufacturers?
It helps them match supply with demand for products like petrol.
