You use a wire screen while using a laboratory burner.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

A wire screen is used while using a laboratory burner to provide a stable surface for placing glassware or other items on top of the burner. It helps to distribute the heat evenly and prevent direct contact between the flame and the glassware, reducing the risk of breakage or damage. Additionally, the wire screen acts as a safety measure by preventing any potential spills or splashes from reaching the flame, minimizing the chances of fire or accidents. Therefore, it is true that a wire screen is used while using a laboratory burner.
