Study Notes
Plasma in Flames
- A flame is considered plasma because it contains ions and free electrons, resulting from the high temperatures that break down the molecular bonds of the fuel.
Composition of the Yellow Part of a Candle Flame
- The yellow part of a candle flame is primarily composed of soot particles, which are small particles of carbon that are formed during the combustion process.
Decomposition of Fuel Molecules
- The process of fuel molecules in candle wax vaporizing in an inert atmosphere without oxidizer is called pyrolysis.
- The vaporized fuel molecules in a flame decompose due to thermal dissociation, where the high temperatures break down the molecules into smaller fragments.
Applications of Higher Parts of a Flame
- Goldsmiths use the higher, hotter parts of a flame to melt and shape metals, taking advantage of the high temperatures and concentrated heat in these areas.
