Why is the blue flame noisier than the yellow flame on a Bunsen burner?
Hbasri1998
because it's burning more violently
a2. In detail, the flame front is a continuous explosion, travelling faster than the local speed of sound. The gas-air mix reaches explosive mixture levels, explodes, but in doing so it now is removed from the region of explosive mixture, and returns to that point by normal burning. Only to reach the explosive mixture point again. many times per second.
