How does a yellow flame on a Bunsen burner make things black but the roaring flame doesn't?
The flame of a Bunsen burner that is yellow in color will leave a black carbon residue due to the incorrect mixture of oxygen into the flame. Because there is not enough oxygen for complete combustion, the carbon reside is left behind. When the Bunsen flame has a sufficient amount of oxygen mixed in, hence the 'roaring flame', it has a blue color and does not leave a carbon residue due to complete combustion of the acetylene gas.

Why does a yellow flame appear on the Bunsen burner when the air hole is closed?
In a laboratory under normal conditions and with a closed oxygen valve, a Bunsen burner burns with yellow flame (also called a safety flame). This is due to the burning of very fine soot particles that are produced in the flame. With increasing oxygen supply, less black body-radiating soot is produced due to a more complete combustion and the reaction creates enough energy to producing a blue appearance flame.

What are the temperatures of the Bunsen burner flame zones?
A Bunsen burner flame consists of an inner cone and an inner cone. In the inner cone, no combustion is occurring and the inner cone consists of a mix of air (which has been introduced through the vents in the bottom of the barrel) and gas. In the outer cone, combustion is occurring. Hence a Bunsen burner flame is "hollow;" there is no flame in the inner cone. Because air, containing oxygen, is present in the inner cone, it is called the "oxidizing zone." A piece of red hot copper held inside the inner cone will oxidize, being covered with a layer of black copper oxide.
