Give reason that the air holes of a gas burner have to be adjusted when the heated vessels get blackened by the flame.

When the vessels get blackened it is due to incomplete combustion. This occurs when the air holes are blocked thus not allowing sufficient supply of oxygen.
Therefore adjusting the air holes can allow supply of oxygen giving a blue flame and avoiding blackening of vessels.
Hope this helps!!
