Answer
The flame colour will be blue when the air hole is open.
Explanation
## Step 1: When the air hole on a Bunsen burner is open, more oxygen can mix with the gas.## Step 2: The maximum amount of oxygen that bunsen burner can intake allows the gas to burn completely, leading to a condition known as complete combustion.## Step 3: During complete combustion, the products are usually water vapor and carbon dioxide. The color of the flame under this condition appears blue because of the complete burning.
