Did you know : Why do substances burn with or without flames?
Have you ever observed either a coal or a wood fire? If not, the next time you get a chance, take a close note of what happens when the wood or coal starts to burn. you have seen that a candle or the
LPG in the gas stove burns with a flame. However, you will observe the coal or the charcoal in an 'angithi' sometimes just glows red and gives out heat without flames. This is because a flame is only produced when gaseous substance burn. when wood or charcoal is ignited, the volatile substance present vaporises and burn with a flame in the beginning.
