Question

Quizplus · Accepted Answer

Heat flows outward from a fire through all three mechanisms - diffusion, radiation, and convection. Diffusion causes the transfer of heat from hotter areas to cooler areas, radiation occurs when heat is emitted in the form of electromagnetic waves from the flames and hot surfaces, and convection causes the hot, lightweight gases to rise and transfer heat. Therefore, all the given choices are correct.
