- 1AlkaneA hydrocarbon with the general formula CnH2n+2
- 2AlkeneA hydrocarbon with the general formula CnH2n
- 3BiodieselDiesel fuel made from plat materials
- 4Crude oilA mixture of different sized hydrocarbons
- 5CrackingThe breaking apart of a long chain molecule using heat
- 6Fractional distillationA way of separating a mixture of substances according to their boiling points
- 7HydrocarbonA compound containing only hydrogen and carbon
- 8Intermolecular forcesForces of attraction between molecules
- 9SaturatedA hydrocarbon which contains as many hydrogen atoms as possible in each molecule
- 10UnsaturatedA hydrocarbon which contains a carbon-carbon double bond
- 11PolymerA substance consisting of very large molecules made of smaller identical molecules called monomers
- 12MonomerA molecule that can combine with other similar molecules to form a polymer
- 13MixtureTwo or more elements or compounds that are not chemically combined together.
- 14FractionsHydrocarbons with similar properties separated by their boiling point
- 15Boiling point/condensation pointTemperature at which a substance becomes a vapor/liquifies
- 16ViscosityHow easily it flows
- 17VolatilityThe tendency to turn into a gas
- 18Sulphur dioxidePoisonous gas produced from impurities in the fuel reacting with oxygen from the air. Can cause acid rain.
- 19CombustionWhen fuels (hydrocarbons) burn in plenty of oxygen to produce carbon dioxide and water
- 20Incomplete combustionWhen not enough oxygen is present during the reaction to produce carbon dioxide. Carbon monoxide a toxic gas is produced instead.
- 21Nitrogen oxidesHigh temperatures of an engine cause nitrogen and oxygen from the air to react. Can cause acid rain.
- 22ParticulatesTiny particles of unburnt hydrocarbons. Cause global dimming.
- 23Greenhouse gasGas which prevents the heat of the Earth being lost by radiation.
- 24Global warmingChanging temperatures around the Earth
