Blue. One way to think of it is to consider visible light. Light with short wavelength has high energy (as you move towards purple from red). So for a flame to be producing a certain colour it needs the energy to create this colour. As blue is closer to purple that green is in the visible spectrum, then the flame must have more energy which must mean the flame is hotter.
What else can I help you with?
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.
Why is the blue roaring flame hotter?
The blue roaring flame is hotter because it indicates complete combustion of the fuel which leads to a more efficient release of energy in the form of heat. The blue color is a result of a higher amount of oxygen present in the flame, allowing for a more intense and hotter burn compared to a yellow flame which indicates incomplete combustion.
Is a yellow flame of a Bunsen burner hotter than the blue flame?
No, a blue flame of a Bunsen burner is hotter than a yellow flame. The blue flame indicates complete combustion of the gas, which produces a higher temperature compared to the yellow flame's incomplete combustion.
Why is it better to use a blue flame on a Bunsen burner?
It is better to use a blue flame on a Bunsen burner because it indicates complete combustion of the gas, resulting in a hotter and more efficient flame for heating or sterilizing purposes. A blue flame also produces less soot and smoke compared to a yellow or orange flame.
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.

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.
What is more powerful a red flame or a blue flame?
blue flames are hotter
Why is the blue roaring flame hotter?

Is a yellow flame of a Bunsen burner hotter than the blue flame?
No, a blue flame of a Bunsen burner is hotter than a yellow flame. The blue flame indicates complete combustion of the gas, which produces a higher temperature compared to the yellow flame's incomplete combustion.
What part of a flame burns hotter?
The blue portion of a flame is the hottest
Is the blue flame hotter then then the yellow flame?
Yes it is. Because it gets more oxygen do therefore its hotter. It burns the air up and becomes blue.
Why does water get hotter when being boiled by a blue Bunsen burner flame?
If you see blue it means that the flame is hotter. It will then (obviously) heat up whatever it is faster.
Is the blue flame hotter than yellow flames?
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 !!
Why is the tip of the flame hotter than the inner part of the flame?
It isn't. The inner (blue) part is the hottest.
Why is it better to use a blue flame on a Bunsen burner?
It is better to use a blue flame on a Bunsen burner because it indicates complete combustion of the gas, resulting in a hotter and more efficient flame for heating or sterilizing purposes. A blue flame also produces less soot and smoke compared to a yellow or orange flame.
How do you find out if the yellow flame in a Bunsen burner is hotter than the blue flame?
take a pencil, a sheet of paper and 1digital themonator and write down the temp of the yellow flame then reset it and take the temp of the blue flame and write down the temp of it then see which one is hotter.
