#1. What do we use for surfacing roads and roofs?
#2. Arrange the following steps in the correct order to describe how crude oil is separated into more useful fractions. 1) When hydrocarbons condense they drip into a tray and are removed in pipes. 2) Bitumen leaves first since it has the lowest boiling point and the column is hotter at the bottom. 3) Kerosene condenses and is removed 4) Fuel oil leaves second, followed by diesel oil 5) As the vapours rise they cool and different hydrocarbons condense due to their difference in boiling points. 6) Petrol condenses and is removed 7) Crude oil is heated until it evaporates and then is pumped into the bottom of a fractionating column. 8) At the top of the column, some gases leave as they have still not condensed.
#3. Why is bitumen not a good fuel?
#4. What do we use for domestic cooking?
#5. What do we use to fuel aircraft?
#6. What do we use to fuel large ships and power stations?
#7. Finish the sentence: Petrol, kerosene and diesel oil are .......... fossil fuels obtained from crude oil.
#8. Hydrocarbons with the longest carbon chains have the highest boiling points. Where are the fractions with the smallest carbon chains removed in a fractionating column?
#9. What do we use to fuel our cars?
#10. Hydrocarbons are compounds which contain which two elements only?
#11. Which of the following statements are correct about crude oil?
Select all that apply:
#12. Complete the sentence: Methane is a ....... fossil fuel found in natural gas.
#13. Hydrocarbons are separated in fractionating columns into fractions with similar properties. Fractions which are not very viscous and so flow easily also ignite easily. Which statement explains how viscosity differs within the column?
#14. Which process do we use to separate crude oil into more useful and simpler mixtures?
