Properties of luminous and non-luminous flames?
luminous flames have a bluish to violet color and it means that the system is given enough oxygen for the reaction. Luminous flames will not produce soot. non luminous flames are orange, red, and yellow much like your everyday campfire but this system is not given enough oxygen therefore produce soot.
Which bunsen burner luminous or non luminous flame used in laboratory and why?
A non-luminous flame is typically used in laboratory settings when using a Bunsen burner. This flame produces a more controlled and homogeneous heat source, making it ideal for processes like heating, sterilizing, and combustion analysis. The non-luminous flame also produces less soot and is more energy efficient compared to a luminous flame.
Formula between Current and luminous intensity?
Any formula relating those two quantities must depend on the technique used to generate light by means of electric current. We know that there can't be one universal formula because, for example, we know that a compact fluorescent lamp uses less current to produce more luminous intensity than an incandescent lamp.
When the Bunsen burner is on but no experiment is being carried out why is it advisable to set it to the luminous flame?
Setting the Bunsen burner to the luminous flame when not in use helps prevent soot buildup on the burner. The luminous flame produces less heat and is less likely to cause accidental burns or ignition of nearby materials in case of a mishap. Additionally, it reduces the risk of gas leakage since the flame is more stable and less likely to flicker.
Are safety razors better for the environment compared to disposable razors?
Yes, safety razors are better for the environment compared to disposable razors because they produce less waste and are typically made of more sustainable materials.
Does a non luminous flame produce a lot of carbon residue?
Yes, non-luminous flames produce less carbon residue compared to luminous flames. These flames have the right amount of oxygen for combustion, resulting in more complete burning of the fuel and less soot or carbon deposit.
What are the advantages of using a non-luminous flame?
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.

How luminous is a white dwarf?
White dwarfs are not very luminous compared to other stars. While they can be thousands of times more luminous than the Sun due to their high surface temperatures, their small size limits their overall brightness. They are often dimmer than main sequence stars of similar mass.

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. The sun is luminous; the moon is non-luminous.
What are the advantages of organic herbs?
less pesticide residue
What kind of sound a low amplitude produce?
Low amplitude sound waves produce quieter sounds that are less intense and have lower volume. They are typically perceived as softer and less powerful compared to high amplitude sounds.
Why are luminous flames preferred?
The temperature is higher and the soot is minimal.
Why cng is called clean fuel?
Compressed Natural Gas is a cleaner fuel because it produce less or neglible amount of residue and smoke. Nowadays, petrol and diesel is being replacedby CNG in transport fuel as it cause less harm to the environment
Why is it advisable to turn a luminous flame to a non luminous flame when the flame is not in use?
Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
