methods of heat movement

Question 1

conduction

Answer 1

in solids –> atoms packed in= atomic vibration
insulators heat most quickly, reach ignition temp fastest
metals dissipate –> transfers to secondary locations quicker

Question 2

convection

Answer 2

gas and liquid by circulation of molecules
in fires, air currents draw O2 to the base increasing ventilation

Question 3

radiation

Answer 3

emission of heat as electromagnetic radiation
does not transfer through molecules

Question 4

flame over

Answer 4

flame spreading horizontally at great speed

Question 5

flash over

Answer 5

radiation induced
transition from a fire in a room to a room on fire

Question 6

direct flame inpingements

Answer 6

a combo of conduction and convection mechanisms
the gas plume transfers heat to new fuel sources = chain reaction
