The meaning of FLAME is the glowing gaseous part of a fire. How to use flame in a sentence.
flame, rapidly reacting body of gas, commonly a mixture of air and a combustible gas, that gives off heat and, usually, light and is self-propagating. Flame propagation is explained by two theories: heat conduction and diffusion.
The high temperature of the flame causes the vaporized fuel molecules to decompose, forming various incomplete combustion products and free radicals, and these products then react with each other and with the oxidizer involved in the reaction of the following flame (fire).
FLAME definition: 1. a stream of hot, burning gas from something on fire: 2. a powerful feeling: 3. an angry or…. Learn more.
It is what causes the visible flame. Flame color varies depending on what you're burning and how hot it is. Color variation within in a flame is caused by uneven temperature. Typically, the hottest part of a flame -- the base -- glows blue, and the cooler parts at the top glow orange or yellow.
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
When a flame burns cleanly like a gas flame, blow torch, or the base of a candle, the heat excites the molecules to release light, usually pale blue, from atomic transitions. That's from quantum mechanics.
Mar 14, 2014 · Any flame requires three ingredients: oxygen, fuel and heat. Lacking even one, a fire won’t burn. As an ingredient of air, oxygen is usually the easiest to find.
noun. burning gas or vapor, as from wood or coal, that is undergoing combustion; a portion of ignited gas or vapor. Synonyms: fire. Often flames. the state or condition of blazing combustion: to burst into flames. any flamelike condition; glow; inflamed condition. brilliant light; scintillating luster.
Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material.
