1. Fossil Fuels

2. Fuel • A substance that burns in oxygen to produce heat

3. Fire triangle

4. 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

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

6. To examine the products of combustion of a hydrocarbon

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

9. Global warming is a result of this greenhouse effect

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

12. 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

15. PREVENTION OF GLOBAL WARMING AND ACID RAIN??

16. How?!
