You adjust a rotatable thing at the bottom, normally there is a hole that will become either closed or open to change the flame.

What is the movable part of a Bunsen burner?
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
When was the first Bunsen burner made?
The Bunsen burner was first invented by a British physicist and chemist called Michael Faraday in the early 19th century. It was than improved by a famous German chemist called Robert Bunsen in 1850. The second Bunsen burner was now safer, easier and more efficient and has an 'air hole' so you could change the flame from a safety flame (the yellow one) to a efficient flame (the blue one).
How does adjusting the barrel on the Bunsen burner affects the flame?
The bottom of a Bunsen burner contains holes that allow air flow. When there is no air flow, the temperature of the flame will be hotter. With the holes wide open, the flame will not be as hot.
Is lighting a Bunsen burner a chemical reaction?
Yes, because a gas is burned - an oxydation reaction. This chemical reaction produces heat as well as carbon dioxide and water vapor as products from methane and oxygen gas. The heat also excites the electrons in the gases it produces, causing them to gain energy and rapidly emit this energy in the form of photons predominately with a wavelength of approximately 475 nm, which we perceive as blue light. The reaction can be described by the following equation: CH4 (g) + 2 O2 (g) => CO2 (g) + 2 H2O (g)
Function of screw lock in Bunsen burner?
The screw is to change between a luminous flame(orange) and non-luminous flame(blue). You should always screw the lock so that it covers the hole first.
How do you change the flame on a Bunsen burner?
To change the flame on a Bunsen burner you need only to open or close the air valve to change the combustion reaction.
What piece of the Bunsen burner has to be moved to change the type of flame useds?
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
Is heating sodium chloride with a Bunsen burner a chemical change?
No. It is a physical change. It only melts.
How do you change the type of Bunsen burner flame?
use the turning dial at the bottom
What is the movable part of a Bunsen burner?
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
How did the Bunsen burner change the world?
so you can heat things up in a lab quickly
How do you operate a Bunsen burner?
You twist the bottom to change it from a safety flame, blue flame or just a normal flame.

What is turned to used to change the type of flame a Bunsen burner produces?
You would turn the collar on a Bunsen Burner so that the holes are exposing the flame to more oxygen to produce a blue flame. Close the holes by turning the collar to turn it back to the yellow (dirty) flame.
