Story highlights. (CNN)The superintendent of the Tennessee school board where a teacher is accused of kidnapping student Elizabeth Thomas has made an appeal to his former employee. If Elizabeth is with you, bring her home, Maury County Public Schools Superintendent Chris Marczak told CNN on Thursday night.
For example methanol (race car fuel) (1 carbon 4 hydrogens 1 oxygen) burns with an almost invisible flame and acetylene (2 carbons 2 hydrogens (cutting torch without the oxygen turned on) burns with a bright yellow flame with clumps of soot raining down.
The yellow color is due to small particles of soot being burned to incandescence. If we need. a hotter flame, which is usually the case, we would need to introduce more oxygen, by. mixing more air with the methane gas before combustion. The hotter the flame, the bluer it. gets.
