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.
What else can I help you with?
Is a blue flame hotter than 500 degrees Fahrenheit?
Yes, a blue flame is typically hotter than 500 degrees Fahrenheit. Blue flames are associated with higher temperatures compared to yellow or red flames because they indicate complete combustion of the fuel.
Is red hotter than orange in flame colors?
Yes, red is typically hotter than orange in terms of flame colors. The color of a flame can indicate the temperature of the fire, with red flames often being cooler than orange flames.
What is hoter ''blue or red fire?
Blue fire is hotter than red fire, as the color of a flame is indicative of its temperature. Blue flames typically burn at higher temperatures due to more complete combustion.
How hot is the yellow flame?
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
Why does the blue flame on a Bunsen burner make metal things red when they are held in the flame for a long time?
The blue flame of a Bunsen burner is hotter than the yellow flame. When a metal object is held in the blue flame for a long time, it absorbs heat and emits light, resulting in the metal glowing red due to incandescence. This happens as the metal reaches a temperature at which it begins to emit visible light.
Is a flame red flame hotter than a yellow flame?
Yes, typically a red flame is hotter than a yellow flame. The color of a flame is determined by the temperature of the burning material. In general, hotter flames appear bluer or white, while cooler flames tend to appear yellow or red.
What is more powerful a red flame or a blue flame?
blue flames are hotter
Is green fire hotter then blue fire?
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.
Is a blue flame hotter than 500 degrees Fahrenheit?
Yes, a blue flame is typically hotter than 500 degrees Fahrenheit. Blue flames are associated with higher temperatures compared to yellow or red flames because they indicate complete combustion of the fuel.
Are blue stars cooler than red stars?
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.
How hot is a green flame compared to other colored flames?
A green flame is typically not as hot as blue or white flames, but hotter than red or orange flames.
Is a blue star hotter than a red giant?
blue stars are hotter
Is red hotter than orange in flame colors?
Yes, red is typically hotter than orange in terms of flame colors. The color of a flame can indicate the temperature of the fire, with red flames often being cooler than orange flames.
What is hoter ''blue or red fire?
Blue fire is hotter than red fire, as the color of a flame is indicative of its temperature. Blue flames typically burn at higher temperatures due to more complete combustion.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
Which star is hotter a red star or a blue star?
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.
Does blue fire mean it's the hottest or coldest or electric?
Blue light is of a higher energy than red light. That means that the fire with the blue light is hotter, as the fire must generally be hotter to generate the blue light. For example, in a gas flame, the blue, which is hottest, is in the middle, and any yellow, orange or red is around the outside.
