Example - Beach sand is a good example for a mixture of silicates. Polymer - A large molecule made up of chains or rings of linked monomer units. Polymers usually have high melting and boiling points. An example - Examples of Polymer would be PVC (poly vinyl chloride)‚ polystyrene‚ and cellulose. Liquid crystal – A liquid having certain crystalline characteristic‚ especially differntoptical properties in different directions when exposed to an electric field. The liquid crystal is the actual image generator that you look at in the

www.igcse.at.ua ORGANIC CHEMISTRY OIL and its many useful PRODUCTS The origin of oil Crude oil is formed from organic material of the remains of plant and animal organisms that lived millions of years ago. These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from
