How does fire transfer heat from flames

WebThe frying pan becomes hotter if we keep that in flame . It is because of the heat transfer from flame to the utensil . When we remove the pan from fire , the pan slowly cools . It is due to the heat transfer from the pan to the surrounding . So we can say that heat is transferred from the hotter object to the colder object . WebThe 4 Stages of Fire Ignition At its simplest, fires begin when combining oxygen with combustible or flammable materials. If not oxygen itself, oxygen compounds or oxygenated gas can be used in its place. When a fire ignites, it’s in the first stage of four. This stage is also known as the incipient stage.
