The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. [2] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3]
A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction made in a thin zone. [ 1 ] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma .
Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
Title page to the first edition. Intended for young beginners, for whom it is well adapted, as an introduction to the study of chemistry. [3]According to Frank Wilczek: . It is a wonderful laying-bare of surprising facts and intricate structure in a (superficially) familiar process — the burning of a candle.

The intensity of the flames was enhanced by drought conditions ... States around the country have pledged resources to the fire fight, but what has made control efforts difficult has been the off ...
Generally, fire retardants are dropped from aircraft or applied by ground crews around a wildfire's edges in an effort to contain its spread. This allows ground crews time to work to extinguish the fire. However, when needed, retardant can also be dropped directly onto flames to cool the fire and reduce flame length. [13]
