What is a yellow flame in Bunsen burner called?
A yellow flame in a Bunsen burner is called a reducing flame. This type of flame has incomplete combustion and can be adjusted to become a blue flame for more efficient burning.
How do you get a smaller flame on Bunsen burner?
To get a smaller flame on a Bunsen burner, slowly close the air hole at the base of the burner to decrease the amount of air mixing with the gas. This will result in a smaller, more controlled flame.
How can you make the height of the flame smaller on a Bunsen burner?
To make the height of the flame smaller on a Bunsen burner, you can adjust the air hole at the base of the burner. By opening the air hole slightly, less oxygen will reach the flame, leading to a smaller and more controlled flame height.
Is the hole open or closed on a Bunsen burner to make a safety flame?
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
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.

Does the Bunsen burner flame roar or burn quietly?
A Bunsen burner flame can both roar and burn quietly, by allowing more oxygen to reach the flame by opening a valve it will roar, by closing the valve the flame will flicker
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.

What is a collar for on a Bunsen burner?
It is used for adjusting the flame
What is the safest flame on a Bunsen burner?
The safety flame on a Bunsen burner is typically the smallest, pale blue flame that has a well-defined inner cone. This flame is less likely to produce soot or cause accidental fires compared to larger, more intense flames.
Which is more useful between an alcohol lamp and Bunsen burner?
A Bunsen burner is typically more useful than an alcohol lamp in a laboratory setting as it can produce higher temperatures and more powerful flames, making it suitable for a wider range of experiments and processes. The Bunsen burner also allows for better control of the flame and is safer to use due to its design.
What is the blue flame of a Bunsen burner for?
The blue flame is caused by allowing more air into the stem of the Bunsen burner - it produces a fiercer, hotter flame. If the air flow is restricted, the flame turns yellowish and is more like a wax candle.
How do you change the flame on a Bunsen burner?
To adjust the flame on a Bunsen burner, first make sure the gas is turned on. Then, slowly open the air vent to let in more oxygen, which will produce a blue, hotter flame. Conversely, closing the air vent will produce a yellow, cooler flame.
