The Bunsen burner would display complete combustion by producing a "roaring" blue flame and it would display incomplete combustion when you close the air valve complete to cut off the oxygen gas supply, thus creating a yellow flame due to the burning of carbon particles (soot).
What else can I help you with?
What are the two colors of a Bunsen burner flame?
The two colours are yellow - when the air-hole is open, and blue - when the air-hole is closed.
What is the colour of a flame on the Bunsen burner when the whole is half open?
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).
Why is a luminous yellow flame on a Bunsen burner often smokey?
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 is the Colour of the hottest Bunsen flame?
The hottest Bunsen flame is blue in color. It indicates complete combustion of the gas due to the high temperature.
When the airhole on the Bunsen burner is open what colour is the flame?
When the airhole on a Bunsen burner is open, the flame color is blue. This indicates complete combustion of the gas.
Why is the Bunsen burner smokeless?
Smoke is a product of incomplete combustion. When used properly a Bunsen burner propduces complete combustion, which is made evident by a blue flame.
Which flame on a Bunsen burner is silent?
The inner blue flame on a Bunsen burner is silent because it has a well-balanced mixture of gas and air, causing complete combustion with minimal noise. The outer yellow flame is louder due to incomplete combustion and turbulence in the flame.
How many distinct cones a properly adjusted nonlaminous flame on Bunsen b?
A properly adjusted nonluminous flame on a Bunsen burner has two distinct cones: the inner blue cone, which is the hottest part where complete combustion occurs, and the outer yellow cone, which is where incomplete combustion occurs.
What are the two colors of a Bunsen burner flame?
The two colours are yellow - when the air-hole is open, and blue - when the air-hole is closed.
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.
What is the colour of a flame on the Bunsen burner when the whole is half open?
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).
What is the function air hole of a Bunsen burner?
The air hole in a Bunsen Burner allows air to mix with the gas prior to burning so that the flame can be adjusted as desired.
What dos a Bunsen burner do when the air hole is clos?
When you close the air valve of a Bunsen burner the flame turns yellow due to incomplete combustion and the ignition of carbon particles (soot).
Why is a luminous yellow flame on a Bunsen burner often smokey?
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.
Which cone gives off more heat on a Bunsen Burner?
A blue cone on a Bunsen burner gives off more heat because it has a higher temperature than a yellow cone. The blue cone represents complete combustion of the gas, while the yellow cone indicates incomplete combustion with lower temperature.
What is the Colour of the hottest Bunsen flame?
The hottest Bunsen flame is blue in color. It indicates complete combustion of the gas due to the high temperature.
Is the yellow flame on a Bunsen burner the unburnt gas?
The yellow flame on a Bunsen burner is due to incomplete combustion of the gas. It happens when there is not enough oxygen present for the gas to burn completely, leading to the production of soot and a yellow flame. Adjusting the air intake can help achieve a blue flame, which indicates complete combustion.
