2. What are the different types of chemical reactions? Combustion Synthesis Decomposition Single displacement Double displacement Acid base http://misterguch.brinkster.net/6typesofchemicalrxn.html http://www.chemistryhelp.info/images/chemical-reactions.jpg
3. What is a combustion reaction? Combustion reaction- when all substances in a compound are combined with oxygen which then produces carbon dioxide and water. http://library.thinkquest.org/2923/react.html http://www2.hn.psu.edu/faculty/dmencer/combustion/combust_app.gif
4. What is the fire triangle? Fire oxygen- oxygen, heat, and fuel http://ehs.sc.edu/modules/fire/01_triangle.htm http://www.bromine-info.org/uploads/images/halogenated_graph.jpg
5. What is activation energy? activation energy- the energy that an atomic system must acquire before a process (of a reaction) can occur. http://wordnetweb.princeton.edu/perl/webwn?s=activation%20energy http://www.chem.ufl.edu/~itl/2045/matter/FG14_013.GIF
6. Why is heat/energy a necessary part of the fire triangle? Because fire requires elements of heat/energy to continue burning. http://www.survivaltopics.com/survival/fire-tetrahedron/ http://www.newflame.co.uk/images/fire-triangle.gif
7. How is the cook top of your stove (not electric) a real life example of a fire triangle? Because it has flames coming out of it and it’s balanced by fuel, oxygen, and heat. http://www.firesafe.org.uk/html/miscellaneous/firetria.htm http://www.yournewhome123.com/images/Cooktop.jpg
8. What is a combustion engine? Combustion engine- an engine in which the combustion of a fuel occurs with an oxidizer (air) in a combustion chamber. http://en.wikipedia.org/wiki/Internal_combustion_engine http://bkachinsky.transworld.net/files/2009/06/internal-combustion-engine1.jpeg
9. (In general) How does a combustion engine work? The expansion of high temperature and pure gases directly applies force to a moveable component engine. http://en.wikipedia.org/wiki/Internal_combustion_engine http://media.photobucket.com/image/combustion%20engine/silverbeam/CSM%20Blog/EngineCutaway.jpg
10. In terms of combustion, how are nascar engines different form street car engines that allow them to operate at much higher speeds? Nascar engines have much more horse power than regular cars. http://auto.howstuffworks.com/question588.htm http://greenfield.fortunecity.com/egret/448/horses/horsepower.gif
11. Hoe does nitrous oxide help engines perform better? When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air and it provides more oxygen. http://auto.howstuffworks.com/question259.htm http://www.hawkinsspeedshop.com/categories/products/images/nos-02001.jpg
12. Provide 1 document example of cheating in Nascar in which something was done illegally to increase the combustion performance of the engine: Cheating with the engine which involves tinkering with the air and another way is mixing some chemicals with the fuel to provide more oxygen http://www.moto-crossing.net/Nascar-Information/Nascar-Cheating.html http://i.neoseeker.com/p/Games/Xbox/Racing/Car/nascar_06_profilelarge.jpg
