ARSON 1 . Fuel Is the material or substance being burned in the combustion process? 2. self-sustained chemical reaction Is a complex reaction that it requires a fuel (gaseous or vapor state), an oxidizer, and heat to combine in a very specific way. 3. Oxygen Those materials that yield oxygen or other oxidizing gases during the process of a chemical reaction. 4. Heat Is the energy component of the fire tetrahedron? 5. Oxygen A colorless, odorless gas and one of the composition of air which is approximately 21 % by volume. 6. Fuel Any substance which reacts chemically with oxygen and produces flames? 7. Heat A form of energy generated by the transmission of some other form of energy, as in combustion or burning. 8. F alse Under the fire triangle theory, there are 4 ways to extinguish fire? 9. fire triangle theory The graphical representation of the three elements of fire is known as? 10. Fire tetrahedron theory Another explanation of the requirements of combustion uses a four- sided figure is called? 11. chemical reactivity The fourth element of the fire tetrahedron explanation is known as? 12. Reducing agent In scientific terms, the fuel in a combustion reaction is known as? 13. Air The oxygen in the _____ in the surrounding area is considered the primary oxidizing agent? 14. Fuel Another term for reducing agent is known as? 15. Heat Another term for temperature is known as? 16. True For combustion to occur there should be four elements that are necessary? 17. Air The oxygen in the _____ in the surrounding area is considered the primary oxidizing agent? 18. Fuel Another term for reducing agent is known as? 19. Heat Another term for temperature is known as?

20. True For combustion to occur there should be four elements that are necessary? 21. Electrical This type of energy can generate temperatures high enough to ignite any combustible materials near the heated area? 22. Mechanical An energy created by friction and compression? 23. Chemical It is the most common source of heat in combustion reactions? 24. Nuclear Heat energy is generated when atoms either split apart or combine? 25. heat of friction Is the movement of the two surfaces against each other? This movement produced sparks being generated? 26. heat of compression Heat is generated when a gas is compressed in a container or cylinder? 27. Fire Technically speaking, _________ is a form of combustion? 28. Heat Known as exothermic reaction? 29. fire gases Are those that remain when other products of combustion cool to normal temperature? 30. flame It is the luminous body of a burning gas which gets hotter and less luminous when mixed with more oxygen? 31. Pyrolosis It refers to the chemical process whereby fire consumes the most solid part of the fuel. It is the thermal decomposition of a solid fuel through the action of heat.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
