It depends what you want to do! A blue flame is typically much hotter than a yellow flame. Sometimes you want to heat something very hot, and sometimes you want to heat something gently... and so you can choose which part of the flame best suits the purpose!
blue flame
Control of the ratio gas fuel/air in the burner.
This is a bit like asking what a stove heats in a kitchen. Stoves heat food. Bunsen burners heat chemicals. Chemists have many different chemicals that they sometimes need to heat for various reasons.
The safety flame on a Bunsen burner is a low, cool flame that helps prevent accidental ignition of flammable materials. It does not produce enough heat to effectively heat an object. To heat an object, the Bunsen burner must be adjusted to produce a hotter, blue flame by increasing the airflow.
A Bunsen burner can be used for heating, sterilizing, and combustion of chemicals in laboratories. It provides a controlled flame that can be adjusted for different types of experiments, such as heating liquids, melting solids, and performing chemical reactions.
A Bunsen burner striker is a tool used to ignite the gas coming out of a Bunsen burner. It produces a spark that ignites the gas, allowing the burner flame to be adjusted and controlled for heating purposes in the laboratory.
For heating water with a Bunsen burner, you would use a blue flame. This is the hottest part of the Bunsen burner flame and provides the most efficient heat transfer to the water.

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.
The Bunsen burner release energy as heat of combustion.
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.
The bunsen burner is used to heat items for experiments using a controllable temperature flame and surface area at which the heat is applied to the vessel.

The Bunsen burner uses a blue flame, which is produced when air and gas mix in the burner tube and are ignited. This blue flame is hotter than a yellow flame and is commonly used for heating in laboratories.
The safety flame on a Bunsen burner is a low, cool flame that helps prevent accidental ignition of flammable materials. It does not produce enough heat to effectively heat an object. To heat an object, the Bunsen burner must be adjusted to produce a hotter, blue flame by increasing the airflow.
The yellow flame on a Bunsen burner is called a "safety flame" or a "luminous flame." This flame is typically used when a lower temperature is required since it produces less heat than a blue flame.
we cn usE bunSen burner ..... so that we coUld leaRn it?!
