Question

what is the difference between blue flame n yellow flame​

Answer 1

Answer:

A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. Incomplete combustion gives a yellow flame and so less energy is released. When combustion is incomplete, a yellow flame is seen. This is because a yellow flame produces a lot of soot.
