This isn't necessarily true. It depends on WHY the flame is blue.
However, it is true that in order for black body radiation (aka cavity radiation) to appear blue, the object it's coming from must be significantly hotter than an object from which the cavity radiation appears red.
Blue light has a shorter wavelength (and therefore a higher energy) than red light, so it requires a hotter object for the blue wavelengths to predominate.
The blue flame is hotter than a yellow flame because it has more oxygen so its stronger and can create more energy and heat the hottest part is right under the center its called the crown!!.
Note- A blue color corresponds to a temperature of about 20,000 degrees and upwards. This is far hotter than any known flame. If some region of a flame does not have enough oxygen to burn completely (lesser temperature as well), it will begin to form tiny soot particles. These soot particles are far more dense than the surrounding gas, so they glow a nice bright yellow color.
More electrons are jumping into a higher energy shell in blue light then in yellow light and so more energy or heat is being produced also yellow light or flame has a larger wavelength then blue so blue is moving more rapidly and producing more energy
A blue flame is hotter than a yellow flame because a blue flame has more oxygen, so it has more energy to create extra heat. Therefore, a blue flame is more dangerous and a yellow flame is used in laboratories. The hottest part of the blue flame is right under the middle, this part is called the crown !!
For the same reason that blue and white stars are hotter than red and yellow ones.
When things burn the constituent parts are separated into their elements which break down to individual atoms. As these get hot they get excited and start to vibrate, giving off energy. This energy reaches levels which is visble to the naked eye. The higher the energy state the further along the visible spectrum the light appears. The lowest temperatures in the visible spectrum is in the red region then orange, yellow until the blue and indigo region is reached. Beyond that the light becomes invisble to the naked eye.
Since all elements have a temperature signature when they burn temperatures can be deduced from the colour of the flame.
I assume you mean burning a flammable gas like butane or propane here.
The yellow flame is an inefficiently burned mixture of gas and oxygen, so less heat is given off. When it is burned correctly the mixture burns blue, and gives off more heat as the mixture burns.
The reason blue flames are hotter than red flames is because blue light waves have shorter wavelengths than red light waves. The shorter a wavelength of light is the more energized it is, and a hotter flame has more energy.
Because the blue fire has less oxygen so it gets alot hotter then the red flame and go f yourself cause this is wrong
Yes, From what i know Red Flames are 1800F...Orange is 2200F... and White is 2700F. I'm Trying to Find out how much it Need for a Pure Blue Fire
yes, they are. here are the flame colors in order from hottest to coolest. white - hottest blue - hotter yellow - hot orange - cooler than yellow red - cooler than all of above
Orange flames are ho
Blue and Red
I took this from Wikipedia(http://en.wikipedia.org/wiki/Fire). Although it doesn't say the temperature at which blue is present but I think it is pretty detailed. * Red ** Just visible: 525 °C (977 °F) ** Dull: 700 °C (1290 °F) ** Cherry, dull: 800 °C (1470 °F) ** Cherry, full: 900 °C (1650 °F) ** Cherry, clear: 1000 °C (1830 °F) * Orange ** Deep: 1100 °C (2010 °F) ** Clear: 1200 °C (2190 °F) * White ** Whitish: 1300 °C (2370 °F) ** Bright: 1400 °C (2550 °F) ** Dazzling: 1500 °C (2730 °F) Here is a more detailed article about flames in general, but if you go down a little into the article there's a pretty detailed little bit about flame color. http://en.wikipedia.org/wiki/Flame
No, yellow is hotter. The progression, from least hot to hottest, goes: black-red, dark red, bright red, light red, orange, yellow, blue, white-yellow, white.
blue flames are hotter
Assuming we're not throwing ions into the flame and the color is due strictly to temperature, the blue flame is hotter.The problem is that flames can be different colors for reasons other than temperature. Specifically, they may contain ionized materials with strong emission lines that color the flame. Probably the easiest example to observe using ordinary household materials is sodium which gives an orangish yellow color (easily seen by dropping a few crystals of table salt into the flame of a gas stove).The reason that hotter flames are blue is that blue light is more energetic than red light. A hotter flame has more energy, and therefore generates more energetic light.

No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.

blue stars are hotter
The sun is hotter than red stars but cooler than blue stars,
A blue flame is hotter than a yellow flame simply because a blue flame has more oxygen to create extra energy,while red flames have less oxygen to create heat.
Orange flames are ho
a blue star is hotter then a red star because it is younger and thus has more energy. a good example of this is when you look at a flame on a lighter you see blue light at the bottom because blue is hottest and closest to the heat source whereas the red-orange flame at the top is farther away from the heat source and thus is not as hot as the blue.
