Fossil Fuels

Fuel A substance that burns in oxygen to produce heat

Fire triangle

Fossil Fuels Formed from the remains of organisms that lived millions of years ago They are composed of mainly hydrogen and carbon and are called hydro carbons

Hydrocarbons. These are compounds that contain hydrogen and carbon only. They burn to produce carbon dioxide and water.

To examine the products of combustion of a hydrocarbon

The greenhouse effect Heat from the sun is trapped by Carbon dioxide and other gases. This causes the temperature of the Earth to rise.

Global warming is a result of this greenhouse effect

Acid rain Sulfur and Nitrogen, emited gases from burning fossil fuels and car exhausts, all dissolve in rainwater making it acidic.

Sulfuric Acid – Sulfur dioxide produced when we burn fossil fuels Sulfuric Acid – Sulfur dioxide produced when we burn fossil fuels. It dissolves in rainwater to make sulfuric acid Nitric acid – Nitrogen produced by car exhausts dissolves in water vapour to form Nitric acid
