What is the hottest flame in the universe?
The dead star at the center of the Red Spider Nebula has a surface temperature of 250,000 degrees F, which is 25 times the temperature of the Sun's surface. This white dwarf may, indeed, be the hottest object in the universe.
Which is hotter blue or white flame?
The color blue indicates a temperature even hotter than white. ... Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.

Is there green fire?
Chemicals and Compounds Can Affect Flame Color Finally, it's worth mentioning that the presence of certain chemicals or compounds can alter the color of a flame. A green flame, for instance, indicates the presence of copper. As copper heats up, it absorbs energy that's manifested in the form of a green flame.
What is the coldest fire color?
The coldest flame color will be black since the flame is so weak that it barely produces light. Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C).

How do you tell if a fire is hot or cold?
As you can tell, there is a direct link between the heat of a flame and the color that a fire burns. Flames that are colder or starting to fizzle away will have a different hue than a raging fire or newly sparked match. The amount of heat and energy released during combustion is tied to the hues of the flames.

Is a blue flame hotter than a yellow flame?
Is a blue or yellow flame hotter? Blue flames aren't always hotter than yellow flames, because the color of light emitted by the flame can depend on exactly which atoms and molecules are in the flame. Sometimes that's more important than the temperature of the flame in setting the color. Similar Asks.
What is the hottest color of fire?
Blue, on the other hand, while representing cooler colors in society, actually epitomizes the opposite in fires as some of the hottest flames all around. When all flame colors combine, they produce white, the hottest color of them all.
What is the hottest flame?
The hottest flame is violet on the color spectrum and white in the visible spectrum. The type of fuel and impurities, in addition to the flame temperature, contribute to the color of the flame. Once the gas forms, combustion occurs as the various molecules react with oxygen to produce the heat and light known as fire.
What is the color of a fire?
Near the logs, where most burning is occurring, the fire is white, the hottest color possible for organic material in general, or yellow. Above the yellow region, the color changes to orange, which is cooler, then red, which is cooler still. Is a blue or yellow flame hotter?
What determines the temperature of a flame?
When looking at a flame's temperature there are many factors which can change or apply. An important one is that a flame's color does not necessarily determine a temperature comparison because black-body radiation is not the only thing that produces or determines the color seen; therefore it is only an estimation of temperature. Other factors that determine its temperature are: 1 Adiabatic flame; i.e., no loss of heat to the atmosphere (may differ in certain parts) 2 Atmospheric pressure 3 Percentage oxygen content of the atmosphere 4 The kind of fuel used (i.e., depends on how quickly the process occurs; how violent the combustion is) 5 Any oxidation of the fuel 6 Temperature of atmosphere links to adiabatic flame temperature (i.e., heat will transfer to a cooler atmosphere more quickly) 7 How stoichiometric the combustion process is (a 1:1 stoichiometricity) assuming no dissociation will have the highest flame temperature; excess air/oxygen will lower it as will lack of air/oxygen
Why is the flame yellow?
The yellow arises from incandescence of very fine soot particles that are produced in the flame. When the air inlet is opened, less soot is produced. When enough air is supplied, no soot is produced and the flame becomes blue. (Most of this blue had previously been obscured by the bright yellow emissions.)
What are the yellow parts of a candle?
One may investigate all the different parts of the flame from a candle with a cold metal spoon: Higher parts are water vapor, the end result of combustion; yellow parts in the middle are soot ; down just next to the candle wick is unburned wax.

Does flame color determine temperature?
An important one is that a flame's color does not necessarily determine a temperature comparison because black-body radiation is not the only thing that produces or determines the color seen; therefore it is only an estimation of temperature. Other factors that determine its temperature are:
What is the difference between a diffusion flame and a premix flame?
In a diffusion flame, oxygen and fuel diffuse into each other; the flame occurs where they meet. In a premixed flame , the oxygen and fuel are premixed beforehand, which results in a different type of flame. Candle flames (a diffusion flame) ...
How are specific colors imparted to flames?
Specific colors can be imparted to the flame by introduction of excitable species with bright emission spectrum lines. In analytical chemistry, this effect is used in flame tests to determine presence of some metal ions. In pyrotechnics, the pyrotechnic colorants are used to produce brightly colored fireworks.

It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, ...
Is a reaction exothermic or exothermic?
The reaction is exothermic, but it’s not extremely so. However since all the heat remains at the reaction site together with the solid reaction products, temperature can be quite high. The maximum achievable temperature is limited by the boiling of the reaction products, as evaporation takes away heat.

Mechanism
Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize (If this process happens in inert atmosphere without oxidizer, it is called pyrolysis). In this state they can then readily react with oxygen in the air, which gives off enough heat i…
Color
Flame color depends on several factors, the most important typically being black-body radiation and spectral band emission, with both spectral line emission and spectral line absorption playing smaller roles. In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the r…
In microgravity
In the year 2000, experiments by NASA confirmed that gravity plays an indirect role in flame formation and composition. The common distribution of a flame under normal gravity conditions depends on convection, as soot tends to rise to the top of a flame (such as in a candle in normal gravity conditions), making it yellow. In microgravity or zero gravityenvironment, such as in orbit, natural conv…
Thermonuclear flames
Flames do not need to be driven only by chemical energy release. In stars, subsonic burning fronts driven by burning light nuclei (like carbon or helium) to heavy nuclei (up to iron group) propagate as flames. This is important in some models of Type Ia supernovae. In thermonuclear flames, thermal conduction dominates over species diffusion, so the flame speed and thickness is determined by the thermonuclear energy release and thermal conductivity (often in the form of deg…
