- 29. it is the transfer of heat by circulation of heated currents of liquids and gases.
- 31. the lowest temperature at which liquid fuel produces a flammable vapor in sufficient quantity such that if a source of ignition is introduced, the vapor will ignite and is usually a few degrees above the flash point
- 32. a colorless flammable poisonous gas with a characteristics smell of rotten eggs.
- 34. it is the luminous body of a burning gas which gets hotter and less luminous when mixed with more oxygen.
- 36. the mechanism in which fire can spread from its origin to other sources of fuel.
- 40. any act that would remove or neutralize fire hazard.
- 43. It is the most common source of heat in combustion reactions.
