Question
Why does the bottom of the inner blue cone of a bunsen burner have such a low temperature compared to the rest of the flames? Is this due to the outside flames being in contact with oxygen, while the inner flame receives a low amount of oxygen?
Answers
The inner cone has no oxygen(it's just pure gas).; therefore, there is no combustion and no heat generated. In fact, the next time you have a chance, take a match and thrust it quickly so that the head of the match is WITHIN the cone that is below the tip and the burner. The match will not ignite. The match STICK between your hand and the match head will catch on fire and eventually that will lead to the match igniting but the heat comes from the match stick and the outer edges of the cone and not from the inner part of the cone.
