C1d
Boiling point ­ temperature at which a liquid rapidly turns to
vapour, water has a boiling point of 100 at
normal atmospheric pressure
Covalent ­ type of bonding between atoms, usually non metal
atoms, involving a sharing of electrons
Cracking ­ breaking down of long chain hydrocarbon molecules by
the action of a heated catalyst or by heat alone to
produce smaller molecules
Crude oil ­ a mixture of hydrocarbons produced by the action of
high temperature and pressures on the remains of sea
creatures over millions of years
Finite resource ­ a resource whose life is limited and whose
supply will run out in the future
Fossil fuel ­ fuel produced from the slow decay of dead animals
and plants at high temperatures and high pressures
Fraction ­ product collected on fractional distillation of crude oil,
a fraction has a particular boiling point range and
particular uses
Fractional distillation ­ method for separating liquids with
different boiling points
Hydrocarbons ­ compound of hydrogen and carbon only
LPG ­ the gas which leaves the top of the fractional distillation
column and is liquefied, it is an alternative to petrol or
diesel in cars
Non renewable fuel ­ a fuel that took a long time to form and
cannot quickly be replaced
Polymer ­ long chain molecule built up of a large number of
smaller units, called monomers, joined together by the
