because it can harm you or your clothes so you should never play around with half open burners they let out blue flame which is very dangerous because it is the dirtiest falme
A gentle flame is not too hot and not too cold, the air hole should be half open for a gentle flame and it makes a hissing sound. Hope this helps- :D xx
The four(4) flame types of Bunsen burner is depending on flow through the throat holes (holes on the side of the Bunsen burner -- not to be confused with the needle valve for gas flow adjustment). 1) air hole closed (Safety flame used for when not in use or lighting). 2) air hole slightly open. 3) air hole half open. 4) air hole almost fully open (this is the roaring blue flame).
A half-opened holed Bunsen burner is typically used to create a controlled flame for heating, sterilization, or combustion in laboratories. The adjustable air supply allows for a mix of gas and air, producing a flame that can be modified for different applications, such as a luminous flame for gentle heating or a non-luminous flame for higher temperatures. This versatility makes it ideal for various experiments and procedures in scientific research and education.
Atleast a half hour.
You do the same test as you would have done in year 7, the pop test. Invert a test tube and fill partially with the gas then place a lit match or candle at the bottom if you hear a pop you have hydrogen. just don't be like my old teacher and fill it to the point half the room catches fire. Hope this helps
Orange??
No, having the air hole half open on a Bunsen burner can lead to an unstable flame. It is important to adjust the air hole based on the type of flame required for the experiment being conducted.
When the air hole of a Bunsen burner is half open, the sound produced is usually a low-pitched roaring noise, indicating that the flame is receiving the right amount of air for combustion. It should be a steady sound, with a stable flame. Adjusting the air hole helps control the intensity of the flame.
The flame in a Bunsen burner with the air hole half open is called a yellow, luminous flame. This type of flame is inefficient as it produces soot and is cooler compared to a blue flame. Adjusting the air hole helps control the type of flame produced by the Bunsen burner.

A half-open flame on a Bunsen burner is used for heating solutions gently. It provides a more diffuse heat compared to a fully open flame, which is useful for tasks where overheating or boiling over needs to be avoided.
The flame on a Bunsen burner will be yellow with a small light blue inner cone when the hole is half open. This indicates a partially open air hole allowing for both incomplete combustion (yellow) and complete combustion (blue).
A hot flame is obtained (but not the hottest) with a color violet-white.
No, the flame will not be steady if the air hole of the Bunsen burner is half opened. Adjusting the air hole affects the air-to-fuel ratio needed for combustion. A half-open air hole may result in an incomplete combustion, leading to an unstable or flickering flame. Adjust the air hole until a steady blue flame is achieved.
A gentle flame is not too hot and not too cold, the air hole should be half open for a gentle flame and it makes a hissing sound. Hope this helps- :D xx
When the hole of a Bunsen burner is half closed (or half open) the flame is mostly blue-violet in color throughout, with no orange/yellow apparent as it would be with the hole fully closed. When the hole is fully open, the flame divides into a pale voilet color outer part with a cone of intense blue color within.
