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.
Give two reasons why the yellow flame is safer on busen burner?
The yellow flame on a Bunsen burner is cooler than a blue flame, reducing the risk of burns or overheating materials. Additionally, the yellow flame produces less UV radiation compared to a blue flame, making it safer for experiments involving light-sensitive materials.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
What is the surface temperature of a yellow star?
The surface temperature of a yellow star typically ranges from 5,000 to 6,000 degrees Celsius. This temperature range is lower than that of hotter stars like blue or white ones, but higher than cooler stars like red dwarfs.
What colour flames is lithium sodium and potassium?
sodium-yellow lithium-red barium-apple green copper-dark green calcium-brick red
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
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 a clue to a stars temperature?
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
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.
Give two reasons why the yellow flame is safer on busen burner?
The yellow flame on a Bunsen burner is cooler than a blue flame, reducing the risk of burns or overheating materials. Additionally, the yellow flame produces less UV radiation compared to a blue flame, making it safer for experiments involving light-sensitive materials.
Why is the blue flame hotter than the red flame?
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 is more powerful a red flame or a blue flame?
blue flames are hotter
What are all colors of fire?
The colors of fire can range from red, orange, and yellow to blue and white, depending on the temperature of the flame. A cooler flame will appear yellow or orange, while a hotter flame will appear blue or white. Other colors, such as green and purple, can also be seen in certain conditions.
Are yellowed colored stars cooler than red colored?
No. Yellow stars are hotter than red stars.See related question.
Is a star that emits mostley yellow visible light hotter than a red star?
Yes.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
