Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue. Hotter flames burn blue and (relatively) cooler ones burn yellow.

Non-luminous flames burn hotter and more efficiently compared to luminous flames. They also produce less soot and are less likely to deposit carbon on surfaces. Non-luminous flames are often preferred for applications requiring high heat intensity and precision.

Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light.

What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
A luminous flame is one that emits light due to incomplete combustion of fuel. It takes longer to heat an equal amount of water using a luminous flame because a significant amount of heat energy is lost as light instead of being transferred to the water. This means less heat is available to raise the temperature of the water, resulting in a longer heating time.
Why must the size of the test flame be kept very small?
Keeping the test flame size small ensures consistent and controlled conditions for conducting the test. A small flame also helps in observing the characteristics of the substance being tested more accurately and allows for better comparison with known standards. Additionally, a small test flame minimizes safety risks and potential variability in results.
What are the advantages and disadvantage of Flame emission?
Advantages of flame emission include high sensitivity, wide dynamic range, and speed of analysis. However, disadvantages can include interferences from other elements, the need for sample preparation, and potential contamination of the flame.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
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.

Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
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.
Why must the size of the test flame be kept very small?
Keeping the test flame size small ensures consistent and controlled conditions for conducting the test. A small flame also helps in observing the characteristics of the substance being tested more accurately and allows for better comparison with known standards.

How can a flashlight can be luminous and nonluminous?
A flashlight can be luminous when turned on, emitting light from the bulb. It can be nonluminous when turned off because at that point it is not emitting any light.

Why is blue the dominant color of a nonluminous flame on a Bunsen burner?
Blue flames on a Bunsen burner are typically hotter than yellow flames because they are more complete combustion of the fuel gas. The blue color indicates that there is enough oxygen present for complete combustion, resulting in a clean and efficient flame. The higher temperature of the blue flame is due to the rapid oxidation of the fuel gas in the presence of oxygen.
