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!

What would the Bunsen burner heat on normal flame?
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.
What is the function of the barrel of the Bunsen burner?
Control of the ratio gas fuel/air in the burner.
What is the main difference of Bunsen burner to alcohol lamp?
Alcohol lamp- is used as a source of heat and light . Bunsen burner- source of heat when non-luminous flame is needed for experimental work..
What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
What is a Bunsen burner striker used for?
It produces a spark which ignites the gas.

Why is a blue Bunsen burner flame better than a yellow flame?
A blue Bunsen burner flame is not necessarily "better". A yellow Bunsen burner flame just shows that it is on, but is usually too big to actually be able to heat something safely. Blue means the flame is smaller (though hotter), and is used to heat.
The uses of Bunsen burner?
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.
How is a Bunsen burner used to identify a substance?
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.

What is a Bunsen burner and what is its function?
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.
What is the function of the barrel of the Bunsen burner?
Control of the ratio gas fuel/air in the burner.
What is a Bunsen burner and use?

What does the moving part of a bunsen burner do?
The moving part of the bunsen burner adjusts the amount of air intake. This changes the appearance and heat of the flame.
What is a Bunsen burner?
A Bunsen Burner is a controlled gas-burning heat source (a "gas candle") that supplies direct heat or flame for scientific experiments and research. (The flame can be blocked by screens to reduce the deposition of soot on test tubes and beakers.)
