Question

Quizplus · Accepted Answer

The three things that must be present for a fire to burn are heat, fuel, and oxygen. The heat provides the activation energy to start the chemical reaction between the fuel and oxygen, leading to combustion and the sustained release of heat and light energy. Without sufficient oxygen, the fire will suffocate and die out. Other factors like wind, pressure, and confinement can influence the behavior and spread of a fire, but they are not essential prerequisites for ignition and combustion.
