Question:
How does fire influence the pressure of the surrounding gases?
Answer:
Heat from a fire increase the pressure of the surrounding gases.
Question:
Whats the difference between heat and temperature?
Answer:
Heat is the thermal kinetic energy needed to release the potential chemical energy in a
fuel. temperature: is the measurement of the heat.
Question:
Contrast the three methods of heat transfer?
Answer:
Conduction: is the transfer of heat through and between solids. Convection: is the
transfer of thermal energy by circulation or movement of a fluid (liquid or gas)
Radiation: is the transmission of energy as electromagnetic waves, such as light waves,
radio waves, or X-rays, without an intervening medium.
, Question:
How are gaseous, liquid, and solid fuel different?
Answer:
Fuel: is the oxidized or burned material or substance in the combustion process. Gases:
for flaming combustion to occur, fuels must be in the gaseous state. Liquids: have a
mass and volume but no definite shape except for a flat surface or the shape of their
container. To burn liquids must vaporize. Solids: have definite size and shape. When
solid fuels are heated, they begin to pyrolize.
Question:
How does oxygen concentration relate to flammability?
Answer:
The more oxygen available, the more energy you get from burning fuel
Question:
How are free radicals produced in the chemical reaction that takes place during flaming
combustion?
Answer:
Sufficient heat during the flaming combustion causes fuel and oxygen to form.
Question:
How do the four stages of fire development differ?
Answer:
Incipient Stage: starts with ignition when the three elements of the fire triangle come
together and the combustion process begin. Growth Stage: As the fire transition from
incipient to growth stage, more of the initial fuel package becomes involved and the
production of the heat and smoke increases. Fully Developed Stage : occurs when all
combustible materials in the compartment are burning at their peak heat release rate
base on available oxygen. Decay Stage: As the fire consumes the available fuel or
oxygen and the heat release rate begin to decline, the fire enters the decay stage.
