A luminous yellow flame on a Bunsen burner indicates incomplete combustion, which can produce soot or smoke. This happens when there is not enough air mixing with the fuel gas, leading to inefficient burning of fuel and the formation of carbon particles that become visible as smoke. Adjusting the air intake on the Bunsen burner can help achieve a cleaner, blue flame with complete combustion.

What are the two kinds of flames produced by Bunsen burner?
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
What is the name of the yellow flame on a Bunsen burner?
The yellow flame on a Bunsen burner is called a "safety flame" or a "luminous flame." This flame is typically used when a lower temperature is required since it produces less heat than a blue flame.
Which flame is not suitable for heating in Bunsen burner?
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
What is the colour of a cool Bunsen burner flame?

What are the two kinds of flames produced by Bunsen burner?
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
What kind of flame are produced by the Bunsen burner?
The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.
Which flame should one use if he is leaving a Bunsen burner unattended?
Luminous since it is visible
How would you adjust the Bunsen burner to obtain a luminous flame?
To obtain a luminous flame on a Bunsen burner, adjust the air intake to decrease the amount of oxygen mixing with the gas. This can be done by partially closing the air hole at the base of the Bunsen burner. This will result in an incomplete combustion of the fuel, producing a yellow, sooty flame.
What colour is the Bunsen burner safety flame?
Yellow/Orange. The blue one is harder to see and hotter.
What is the name of the yellow flame on a Bunsen burner?
The yellow flame on a Bunsen burner is called a "safety flame" or a "luminous flame." This flame is typically used when a lower temperature is required since it produces less heat than a blue flame.
What is another name for the Bunsen burner?
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
What is the name when the air hole is closed on a Bunsen burner?
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
Which flame is not suitable for heating in Bunsen burner?
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
What is the colour of a cool Bunsen burner flame?
A cool Bunsen burner flame typically appears yellow.
What are the characteristics of the luminous Bunsen flame?
A luminous flame is blue and is air/oxygen rich and occurs when the Bunsen vent is open. A non-luminous falme is very yellow and smoky and is fuel rich. It occurs when the Bunsen vent is closed.
