fuels are. Task 1: Extension New Information for Task 1
Watch presentation_001. Now write down one thing you know about
fossil fuels Share your answer with a partner. Pairs feed back one
of their answers to the rest of the class, passing if their answer
has already been given. Fossil fuels were formed from the remains
of dead plants and animals, that lived million of years ago.
Burning fossil fuels - gases
Natural gas (methane) is a fossil fuel. LPG Propane and butane are
the liquefied petroleum gases (LPG) most commonly used. Propane has
a variety of uses, including heating homes, and as a fuel for
vehicles. Butane is sold as camping gas. Demonstration Burning
fossil fuels
Petrol, paraffin and diesel are examples of liquid fossil fuels.
Coal is a solid fossil fuel. Task 1: Answers What are fossil
fuels?
Name the fossil fuels mentioned so far (7). Fossil fuels were
formed from the remains of dead plants and animals, that lived
million of years ago. Natural Gas (Methane), LPG (Propane), Camping
Gas (Butane), Petrol, Paraffin, Diesel and Coal How can I improve

Task 2 (Grade B) Task 2: Describe: How crude oil is separated into
fractions The main fractions obtained from crude oil Task 2:
Extension Keywords for Task 2: hydrocarbons non-renewable resource
finite resource New Information for Task 2
Crude oil is: the source of liquid fossil fuels. a mixture of
hydrocarbons. a non-renewable resource. a finite resource. Explain
what the words in WHITE mean. Hydrocarbons are compounds made from
hydrogen and carbon ONLY. Crude oil is a non-renewable resource,
because
.. it has taken millions of years to form from the remains of
plants and animals. Renewable resources must be .. replaceable
within a reasonable amount of time (days to years). Crude oil is a
finite resource, because .. there is only so much of it on planet
earth, and eventually it will be all used up. Fractional
distillation of crude oil
Small molecules: Low boiling points Very volatile Flows easily
Ignites easily LPG Petrol Crude oil is a mixture of HYDROCARBONS
and these can be separated due to differences in their BOILING
POINTS. Large molecules: high boiling points not very volatile
viscous does not ignite easily Note: this may not match that given
in the text book Task 2: Summary Copy and complete:
Crude oil is a mixture of many different hydrocarbons. Crude oil is
separated by fractional distillation. Fractions containing mixtures
of hydrocarbons are obtained. Each fraction contains many
substances with similar boiling points. 2. The fractions collected
from the cooler top to the hotter bottom of the fractional
distillation column are: LPG, petrol, paraffin, diesel, heating
oil, fuel oil, bitumen Use their first letters to make a rhyme to
help you remember them. How can I improve on task 2?
