Flames

In this lesson, I learnt about different types of flames and their properties.I learnt that there are 2 types of flames- luminous and non-luminuos flame. Luminous flames are produced when air- holes are closed,there are insufficient air so the gas does not burn completely.The non-luminous flameare produced when air-holes are open, so there is enough air for the gas to burn completely. I also learnt that when there is too much air entering the air-hole, it will cause a strike back.
