Correct Answer-conduction, convection, and radiation what is convection? Correct Answer-the transfer of heat energy by the movement of heated fluids or gases, usually in an upward direction what is radiation? Correct Answer-the transmission or transfer of heat energy from one body to another body at a lower temperature through intervening space by electromagnetic waves, such as infrared thermal waves, radio, or x-rays. what are the stages of fire development? Correct Answer-incipient, growth, fully developed fire, and decay what is a rollover? Correct Answer-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 what is a flashover?
