ANS conduction, convection, and radiation
31. what is convection?
ANS the transfer of heat energy by the movement of heated fluids or gases, usually in an upward direction
32. what is radiation?
ANS the transmission or transfer of heat energy from one body to another body at a lower temperature through intervening space by electromag- netic waves, such as infrared thermal waves, radio, or x-rays.

ANS a condition where the unburned fire gases accumulated at the top of a compartment ignite and flames propagate through the how gas layer or across the ceiling
35. what is a flashover?
ANS stage of fire at which all surfaces and objects within a space have been heated to their ignition temperature and flame breaks out almost at once over the surface of all objects in the space
36. what is a backdraft?
ANS instantaneous explosion or rapid burning of superheat- ed gases that occurs when oxygen is introduced into an oxygen-depleted confined space
37. what are the reasons for ventilation?
ANS life safety, fire attack and extinguish- ment, fire spread control, reduction of flashover potential, reduction of backdraft potential, and property conservation
38. what is natural ventilation?
ANS techniques that use the wind, convection cur- rents, and other natrual phenomena to ventilate a structure without the use of fans, blowers, or other mechanical devices
