Fire and flame are two words that often evoke images of both destruction (through wildfires) and the safe use of energy (through a gas stove). However, many people confuse these terms and believe that they are the same thing. While there are similarities between fire and flame, there are also significant differences that will be discussed in this article.
Key Takeaways
- Flame is the visible part of a fire, while fire is the rapid oxidation of materials caused by combustion.
- Flames are hot, glowing gases, and their color depends on the material burning and the temperature of the fire.
- Fire can be controlled, as in a gas stove, or uncontrolled, as in a wildfire.
We all think we know what fire is – it is the oxidation of organic material in the process of combustion, which releases energy in the form of heat and light. In contrast, flame is the visible part (light) of the process called fire. This type of rapid oxidation is different from other types, such as corrosion, where the process is slow and not accompanied by any flame or heat. Flames are actually gases that are burning and are at very high temperatures. The color of the flame depends on the material that is burning and the intensity of the fire. For example, when fire is controlled, such as in a gas stove, the flame will be blue with a yellow-red center. However, when fire is uncontrolled, such as in a forest fire, the flames will be reddish and yellow. The color of the flame is always indicative of the temperatures that are generated in the process of fire.
Flame is the visible part of a fire that is in a gaseous state. When temperatures become too high, the flame can reach a plasma state as the burning gases become ionized.
Firefighters bravely save lives by extinguishing fires that engulf buildings and other structures. These individuals wear special fabrics that are flame-resistant and treated with chemicals called fire retardants. Although these terms may sound similar, they have different properties. A fabric is considered flame-resistant when it resists ignition and can extinguish itself if ignited. A fabric is made flame-resistant by using chemical substances that are fire retardants. A firefighter can pass through naked flames when wearing flame-resistant clothes and an oxygen mask, as their clothing is designed to resist the effects of fire for a longer duration than ordinary clothes.
