when you are doing an experiment that involves "the effect of heat on a ..."
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.
A blue flame on a Bunsen burner is used for heating applications that require a high temperature and clean combustion, such as sterilizing, heating chemicals, or performing lab experiments that require intense heat.
To burn off anything present that may alter the colour of your test.
The yellow flame is considered a safe flame. If you are using the Bunsen to heat you would open the air vent so the flame turns blue, try heat on a yellow flame and it'll end up covered in soot.
The flame test lab is a non-destructive test because it does not destroy the sample being tested. It involves observing the color of the flame produced when a sample is exposed to heat, which can help identify certain elements present in the sample.
A Bunsen burner is used in the lab to provide a controlled flame for heating, sterilizing, or conducting chemical reactions. It offers an easily adjustable flame, making it suitable for a variety of laboratory applications.

The lab apparatus placed on top of the barrel of a burner to spread the flame is called a bunsen burner head or bunsen burner nozzle. It typically features air holes that allow for the mixing of gas and air, enabling a more efficient and controlled flame. This design helps achieve a hotter flame by ensuring proper combustion.

A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.
A Bunsen burner is commonly used for heating, sterilization, and combustion in a science lab. It provides a consistent and adjustable flame that can reach high temperatures for various lab procedures.
