heat excites atoms and photons are released
The luminosity of a flame is the amount of visible light it emits. It varies depending on factors such as the type of fuel being burned, the temperature of the flame, and the presence of impurities. Flames with higher luminosity appear brighter.
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.
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 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.
I was enthralled by the luminosity of the deep water jellyfish.
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.
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.
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.
