The color of a flame is determined by its temperature. Yellow flames are cooler and contain more soot particles, which emit visible light when heated. Blue flames burn hotter and more efficiently, resulting in fewer soot particles and a lack of visible light.
Flames change colour according to what is being burnt and whether it is complete or incomplete combustion. Blue flames usually come about due to gas being burnt as that is complete combustion so all of the gas is burnt with no bi-products. Yellow flames however, the ones that usually come about due to wood being burnt come about because of the soot (carbon) produced when it is burnt. The soot burning is what produces the yellow flames. Flames can be all sorts of colours though, for instance, if you burn copper oxide then the flame will be green.

How do you obtain blue flame on burn-sen burner?
To obtain blue flame on a Bunsen burner, ensure the air hole is fully open and adjust the gas flow to the desired level. A blue flame indicates complete combustion, which requires the right balance of gas and air. Adjusting these factors will help produce a blue flame.
What colour does ethene burn?
Ethene burns with a blue flame.
How do you get a blue flame with the Bunsen burner?
To get a blue flame with a Bunsen burner, ensure the air intake is fully open by turning the collar at the base of the burner counterclockwise to allow more oxygen into the mixture. Adjust the gas flow to achieve a blue, well-defined flame with minimal yellow tip. If the flame is too yellow, increase the air intake until it turns blue.
Why the LPG gas flames are blue in colour?
The blue color of LPG gas flames is due to complete combustion. When LPG burns efficiently, it produces a blue flame because all the carbon in the fuel is fully oxidized to carbon dioxide, resulting in a clean burn. If there are impurities or incomplete combustion, the flame may appear yellow or orange due to the presence of unburned carbon particles.
How hot is the yellow flame?
yes, they are. here are the flame colors in order from hottest to coolest. white - hottest blue - hotter yellow - hot orange - cooler than yellow red - cooler than all of above
What is 4 differences between a yellow safety flam and a blue heat flame produced by a Bunsen burner?
A yellow safety flame is cooler and produces less heat compared to a blue heat flame. The yellow safety flame is typically used for heating or sterilizing items, while the blue heat flame is used for more intense heating or combustion reactions. The yellow safety flame is produced when the air inlet on the Bunsen burner is partially closed, whereas the blue heat flame is produced when the air inlet is fully open. The yellow flame has incomplete combustion due to limited oxygen supply, while the blue flame has complete combustion with sufficient oxygen.
Difference between blue flame and yellow flame?
A blue flame is typically indicative of complete combustion, where the fuel is burning efficiently with sufficient oxygen. In contrast, a yellow flame is a sign of incomplete combustion, suggesting that there is not enough oxygen for the fuel to burn completely, leading to the production of soot and potentially harmful byproducts.
Is a yellow flame of a Bunsen burner hotter than the blue flame?
No, a blue flame of a Bunsen burner is hotter than a yellow flame. The blue flame indicates complete combustion of the gas, which produces a higher temperature compared to the yellow flame's incomplete combustion.
How do you obtain blue flame on burn-sen burner?
To obtain blue flame on a Bunsen burner, ensure the air hole is fully open and adjust the gas flow to the desired level. A blue flame indicates complete combustion, which requires the right balance of gas and air. Adjusting these factors will help produce a blue flame.
Does the blue flame on a Bunsen burner need the air hole open or shut?
It needs to be open to create the hot, blue flame that roars. If the air hole is shut, the flame will burn yellow, similar to a candle.
Why is candle flame yellow?
candles burn with a yellow flame because its an incomplete combustion
Is the blue or yellow flame noisier on a Bunsen burner?
The Blue Flame Will Be Noisier. The Yellow Flame Is Called A Safety Flame Because Everyone can See it. There Are Two Blue Flames: Medium Roaring The Roaring Flame Has A Blue Cone In The Middle Of The Flame And It Is The Hottest. It Also Has More Oxygen. But Overall, The Blue Flames Will Be Noisier Than The Yellow Flame.
How do you get blue flame to yellow flame?
To change a blue flame to a yellow flame, you can adjust the air mixture going into the gas burner. Increasing the amount of air mixed with the gas will result in a yellow flame. This can usually be done by adjusting the air shutter on the burner.
Which flame has more heat a steady blue flame or a yellow flame?
Blue flame. because it does not have carbon
What is thand blue flame?
A blue flame is created when a fuel burns efficiently and completely, producing a clean and hot combustion reaction. This means that there is enough oxygen present for the fuel to burn cleanly, resulting in the blue color of the flame. The blue flame is typically hotter than a yellow or orange flame.
What colour does ethene burn?
Ethene burns with a blue flame.
What is one hazard with the blue flame?
Yellow flame means there's not enough air to completely burn all the fuel, so more carbon monoxide is formed. - - - - - It isnt the blue flame is more dangerous because you cannot see it.
