Where does Bunsen burner's energy come from?
A Bunsen burner's energy comes from the combustion of a fuel source, typically natural gas or propane, which produces a flame. The flame is controlled by adjusting the air and gas mixture to create a steady source of heat for laboratory purposes.
Who discovered the Bunsen burner?
The Bunsen burner was not discovered, but rather invented by Robert Wilhelm Bunsen, a German chemist, in the 19th century. Bunsen developed the burner as a more controlled method for producing a consistent flame for laboratory experiments.
Where is the hottest part on the safety flame on a Bunsen burner?
The hottest part of the flame on a Bunsen burner is at the tip of the inner blue cone. This part of the flame is where combustion is most complete, resulting in the highest temperature.
What is the collar on a Bunsen burner for?
The collar on a Bunsen burner is used to control the airflow to the flame. By adjusting the collar, you can change the ratio of gas to air, which can affect the size and intensity of the flame produced.

What colour should the flame be on the Bunsen burner when you are not using it?
The flame on a Bunsen burner should be blue when not in use. If the flame is yellow, it may indicate a problem with the burner, such as not enough air mixing with the gas, which can be a safety hazard.
What colour is a very hot flame on a Bunsen burner?
Blue and purple
What colour is zinc chloride when in contact with the flame of a Bunsen burner?
Zinc chloride emits a bluish-green flame when in contact with the flame of a Bunsen burner.
How do you obtain a flame from a Bunsen burner?
You turn the air admittance ring at the base of the Bunsen burner until it is fully open. this allows the hottest flame to be produced and has a blue colour
Is there a flame at the top of a Bunsen burner?
No, the flame of a Bunsen burner does not have a visible flame at the top. The blue flame is the hottest part of the flame and is seen just above the burner.
What is the colour of the flame when the hole is fully open on a Bunsen burner?
The flame will be blue when the hole is fully open on a Bunsen burner. This is because the complete combustion of the gas produces a hotter flame with a blue color.
How cold can a Bunsen burner flame be?
A Bunsen burner flame can reach temperatures up to around 1,500 degrees Celsius (2,732 degrees Fahrenheit).
