why does a candle light up a room while a flame from a gas stove doesn't?

Answer 1

Flames are line emitters. Their energy comes from the combustion of particular gases with oxygen, which releases light of characteristic frequencies. Your eye is more sensitive to some frequencies than to others.

A stove usually burns mostly propane gas, which has a blue flame. Candle wax is a mixture of long paraffins, each sort of which has a spectral signature, but a large fraction of the radiation occurs in the yellow part of the spectrum.

So even though a blue propane flame is hotter than a candle flame, the candle flame has a greater percentage of its light in the yellow part of the spectrum that your eye sees best.

Answer 2

A candle uncovered emits light, while a flame from a gas stove is hidden and only used to ignite a cook top, range heater etc. The flame from a gas stove is not out in the open where it can emit light. Just as those of us who are Christians are to be the light of the world. I'm letting my light shine...how about you?

Jesus said in Matthew 5:14-16 (KJV) Ye are the light of the world. A city that is set on an hill cannot be hid. {15} Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. {16} Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. "This little light of mine, I'm gonna let is shine" is more than a song. It is our responsibility as a believer. If you are a believer that light is in you. Don't hide it. Let it shine.

Answer 3

The light from a candle flame comes from glowing carbon particles (soot) heated by the flame reaction. These particles result from incomplete combustion of the complex molecules of candle wax. A gas flame from a stove, either natural gas (methane) or other pure hydrocarbon (propane) does not have much carbon because those compounds burn completely (to CO2 and water), leaving no carbon particles to glow.

For evidence of this, put a cold metal object momentarily in a candle flame, and you will see the black carbon deposit. The same does not happen in a gas flame.

Answer 4

It has to do with the temperature of the flame. A candle burns at a certain temperature, producing a lot of red and yellow light, which is very visible to us. A gas stove burns much hotter, and produces blue light which is not as easy to see by.

Answer 5

a gas stove is an example of near perfect combustion.

the energy released is almost entirely infrared radiation which cannot be seen only felt. from far away, a propane or natural gas flame is nearly invisible too.

a candle flame emits a larger portion of its energy in the form of visible light than a stove flame.

Answer 6

gp4rts is the only one that has it right. Candle and lantern flames glow brightly because of the impurities in the flame. A stove flame is pure gas and doesn't give off much light for the same reason hot air wouldn't give off much light.

Answer 7

A gas stove burns gas in the blue region of the spectrum, while a candle offer you "more light" -in the form of the full spectrum...the candle has more white light. With a longer range of colors, your eyes can see more details, as more objects around the candle reflects their given "colors". this is why only blue will allow a limited amount of objects arount the candle's area to reflect.....makes sense?

Answer 8

The LPG gasoline burning on your range is a Saturated Hydrocarbon which receives sufficient oxygen for burning. that's why it burns blue. Paraffin wax in candles are Unsaturated Hydrocarbons. that's why they are no longer getting sufficient Oxygen for burning and reason a vibrant yellow flame to style and launch Carbon Dioxide on combustion. the clarification why a candle is brighter than an LPG range is because of the fact that Blue mild is of lots larger frequency than Yellow mild emitted from the candles. which potential it has a lots decrease wavelength than the yellow mild. lighting fixtures with decrease wavelengths do get meditated exact and are absorbed via different components in a phenomenon noted as the Photoelectric consequence. that's the comparable clarification why they use pink lighting fixtures as supply up alerts. so as that it may rip by using thick mist and fog. final analysis is, decrease wavelength(as in case of blue) equals dimmer mild. larger wavelength(as in case of yellow) equals brighter mild.
