What makes a gas flame luminous?
A gas flame appears luminous when its temperature is high enough to excite and emit light in the visible spectrum. The presence of soot or other particulates in the flame can also contribute to its luminosity by scattering light. The type of gas being burned and the combustion conditions (such as airflow) can also influence the luminosity of a gas flame.
Flame luminosity with the combustion process?
Flame luminosity in a combustion process is caused by the emission of light from the hot gases and particles produced during the burning of a fuel. The intensity of the flame's brightness can be influenced by factors such as the type of fuel, the presence of certain chemicals in the fuel, and the availability of oxygen for combustion. Brighter flames typically indicate a more efficient and complete combustion process.
What is the degree hotness of non luminous flame?
A non-luminous flame, typically produced by complete combustion, can reach temperatures of approximately 1,200 to 1,500 degrees Celsius (about 2,192 to 2,732 degrees Fahrenheit). This flame is usually blue or clear, indicating efficient burning of fuel with minimal soot production. The absence of luminosity is due to the lower presence of unburned carbon particles, which emit light in luminous flames.
How do you measure the distance to a cepheid?
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

Why is the suns luminosity 1?
A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 1026 W, or 3.839 × 1033 erg/s.So dividing one solar luminosity with the Suns luminosity gives 1.Also it is a lot easier talking about a luminosity of 1 rather than 3.838 x 1026 W, the same way astronomers use 1 AU to mean 150,000,000km.
What causes the luminousity of a flame?
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
How do you account for the luminosity of the flame?
heat excites atoms and photons are released

What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
How does luminous flame exist?
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
What are the characteristics of blue flame in a Bunsen burner?
A blue flame in a Bunsen burner is characterized by its high temperature, clean and efficient combustion, and low luminosity. It is produced when the air intake is adjusted to provide the optimal ratio of gas to air for complete combustion, resulting in a steady, non-luminous blue flame.
How is star luminosity measured?
A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.
Total light output of an object is called?
Luminosity
What is luminosity of the Rigel?
Rigel has a luminosity of 117,490 solar luminosities.
Who is the guy in the Luminosity commercial?
Michael Emerson is in the Luminosity commercial.
What is a sentence with luminosity?
The stars shone with a luminosity reminiscent of diamonds on black velvet .
