What does the blue flame of a gas stove indicate?
Answer and explanation

A blue flame indicates that the fuel is receiving sufficient oxygen and is undergoing complete combustion. Complete combustion of cooking gas generally produces carbon dioxide and water with little or no soot. In contrast, insufficient oxygen causes incomplete combustion, which may produce a yellow flame and soot.
