I want to know the colors of fire at different temperatures

Most people know about fire, but how hot is fire? You don't know? I'm also quite curious, so I went to Qimo to search for knowledge about fire temperature for your reference. The color of the fire element changes with its temperature. When the temperature is below 1000°C, the color of the fire is reddish; in the range of 1000-2000°C, the fire color also becomes lighter and more yellow when the temperature exceeds 2000°C, the flame takes; on a light cyan color; as the temperature increases. Continuously increasing, the fire element which reaches 6000°C emits intense white light. To complete your answer, different fuels burn at different temperatures, and the color of the flame is of course different. However, the determining factor is not the “quality” of the fuel itself, but the “quantity” it produces. Even if the fuel is the samebut in different environments, the flame color will be different. Taking a domestic gas stove as an example, there is an air regulating port under the base of the stove. If the gas and air are mixed properly, it will be normal. The flame is green with a little yellow. When the air is not sufficiently mixed, because combustion is incomplete, you will see a yellow light. Of course, if you add chemicals during the burning process, you can change the color, like lighting a firework. 1. The flame of a candle The flame of a candle does not have just one color, but is mainly yellow. When the candle wick is lit, the heat of the flame will first melt the solid wax into a liquid state, and the liquid wax will rise along the candle wick by capillary phenomenon, and then become gaseous after been heated by the flame. the flame that we see, it burnsIt's actually gaseous wax. The flame of a candle can be divided into three parts: the outer flame is lighter in color, the inner flame is increasingly brighter, and the core of the flame is darker in color. 2. When the flame of the alcohol lamp lights the alcohol lamp, the liquid alcohol in the bottle rises along the wick by capillary phenomenon and evaporates into gas when heated, so it can burn. Therefore, the flame of the spirit lamp is there. identical to that of a candle and can be divided into three parts, and mainly **. 3. Gas flame Since gas is a gas, it can burn directly and produce flames, so the color of the gas flame is only divided into two parts: the inner layer and the outer ring. The color of the flame is blue because the oxygen supply is sufficient for combustion and the temperature is relatively high (around 2500°C). 4. The flame ofa stick of wood When wood burns, it first smokes, then a flame begins to burn. This is different from the process of transforming a candle from solid to liquid and then from liquid to gas. directly from solid to gas and burns. But its flame is the same as the candle flame, and it is also divided into three parts, mainly **. “Knowledge Supply Station” Why are the colors of candle and gas flames different? A candle flame is green, while a gas flame is blue, mainly because of the temperature difference. A low temperature fire appears red or green, while a high temperature fire appears blue. The temperature of the candles is around 1400°C and the temperature of the gas flame is around 2500°C, so the colors of the two are different. When the temperature reaches a certain level, a colored light is emitted, called fiery red (2,000 to 3,500 degreesés Celsius) and orange (3500 to 460 degrees Celsius).0 degrees Celsius) Yellow (4600-5700 degrees Celsius) Yellow-white (5700-7400 degrees Celsius) White (7400-11500 degrees Celsius) Blue-white (11500- 25000 degrees Celsius) Blue (above 25000 degrees Celsius) So generally the center of the flame is blue and the temperature is relatively high and low. Fire represents destruction in nature, but it is followed by rebirth. Because the ashes after combustion are good fertilizers, fire is considered the power of metabolism in nature. The most primitive source of fire for human beings is nature, such as lightning, volcanoes, etc., and then continues to burn after making fire. Later, after the invention of flint and steel, by drilling wood for fire, etc., humans were able to do this. create fire. Flame comes from temperature, and the most common cause of high temperature is combustion, because combustion converts a large amount of chemical energy into thermal energy. So the way to create a fire is to let the material reach the ignition point and burn. Overtime: 2006-04-13 12:08 Fire VS Fireworks: Fires are red, blue, green... and there are many colors. The color of the fire will be different depending on the temperature. Like a gas fire, yes. it turns red, this means incomplete combustion. As for the different colors of fireworks, they are due to the addition of different chemical components that will produce different burning colors, which are very beautiful~~ The fire temperature is low. and the low temperature fire should be about 40 to 50 degrees

You can directly It can burn your hands without hurting your hands

Add alcohol in an appropriate proportion of water

The flame produced should be blue rather than red

A friend once answered False

LThe color of the flame is different

Yes, the temperature is also different

But it is not the lowest temperature of the red light.

This should be the lowest temperature of the blue light. The fire temperature is classified from bottom to top as follows: Blue

Red

Yellow

White (transparent) Some people may ask

What is the temperature of the fire?

The temperature of the flame is only a few hundred degrees because the heat is dissipated into the air and the hot air will rise quickly. and remove the heat. Therefore, the flame temperature will not be too high when heating other objects because the objects are solid. Heat builds up on objects and continues to increaseer. The principle of gas welding is to allow the fuel gas to burn quickly to accumulate a large amount of heat in a short time. In short, the temperature is high. The degree to which it can be heated has nothing to do with the fuel, only the burning rate and heat dissipation conditions.

The temperature of the fire is not constant. The fire temperature is generally above 1000 degrees. The temperature of a wood fire can reach over 1,000 degrees. Volcanic lava mainly occurs between 800 and 1300℃; the candle flame temperature is about 1400℃; the gas flame temperature is 1700℃
