Why are fireworks colorful?

When the flame temperature is 3000 degrees Celsius it is orange, when the flame temperature is 5000 degrees Celsius and 6000 degrees Celsius it is blue.

The essence of a flame is a high-temperature gaseous or plasma substance. There are two factors that determine the color of a flame:

1. The temperature of the flame determines the color of the flame, and the flame is a reaction.

At low temperatures, it is infrared, and as the temperature rises, the flame changes from red-orange (3000 degrees) to yellow-white (4000 degrees) to cyan blue (5000 6000 degrees) to purple (7000 degrees or more) to finally invisible ultraviolet rays (tens of thousands of degrees).

From the perspective of high-energy physics, the flames in the infrared and colored spectral bands are all low-energy flames, and the temperature continues to be high, and the color of the flame ranges from ultraviolet rays to X-rays to gamma rays, etc., which are indescribable "colors".

2. The elemental composition of gaseous and plasma substances determines the inherent spectrum of flames, and each element in the element table will emit its own specific light color at high temperature, such as sodium will appear yellow, potassium will be purple, copper will be green, and the light color of the compound is a variegated color, because there are many kinds of elements that are emitting. This is also the reason why the colors of the various flames are different.

Introduction to Flames

Flame is a state or phenomenon in which a combustible gas is burning, emitting, heating, flickering and rising. A flammable liquid or solid must be turned into a gas before it can be burned to produce a flame.

It is mainly due to the oxidation of combustible gas by air or simple oxygen. Oxygen is not necessarily required for the combustion of some substances, such as the reactive metal magnesium, which can be burned in carbon dioxide and nitrogen.

Question 9: What are the colorful fireworks like, write a metaphor to celebrate These colorful and dazzling fireworks are sprinkled on the world like a goddess scattering flowers!

Question 10: What do the colorful fireworks look like? The colorful fireworks bloomed in the sky like flowers.

Fireworks will have different colors, because the bottom of the fireworks is filled with black gunpowder, and the fireworks ball is filled with luminescent agent and coloring agent, the luminescent agent is aluminum powder or magnesium powder, and the coloring agent is some ordinary metal salts. When fireworks burn in the sky, the luminescent agent and chromic agent in the fireworks ball emit various colored lights at high temperatures.

For example, sodium nitrate and bicarbonate will emit yellow light, strontium nitrate will emit red, barium nitrate will emit green, copper nitrate, copper sulfate will emit blue light, and so on. In order to burst the fireworks, the luminescent agent and the chromic agent are fully burned, and the fireworks ball is also filled with an incendiary agent.

Fireworks refer to the various colors of sparks emitted when a pyrotechnic agent is fired, and sometimes refers to the pyrotechnic agent itself. There are two types of fireworks: small fireworks on the flat ground and large fireworks in the air. Generally, it is a bandaging product with a drug.

When lit, fireworks are sprayed, taking on a variety of colors and creating a variety of scenes. It began in the Song Dynasty. Nowadays, it is also known as "ceremonial flowers" and is commonly used in festivals.

Fireworks are a favorite amusement project for people throughout the ages, because the fireworks are dazzling and dazzling, and they are incomparably brilliant in the night sky, which will give people a strong festive shock! The blooming scene blooms instantly, changing and grabbing people's hearts and souls, making people dizzy.

The essence of a flame is a high-temperature gaseous or plasma substance.

There are two factors that determine the color of a flame:

1. The elemental composition of gaseous and ionic substances determines the inherent spectrum of flames, and each element in the element table will emit its own specific light color at high temperatures, such as sodium will appear yellow, potassium will be purple hand group, copper will be green, and the light color of the compound is a variegated color, because there are many kinds of elements that are emitting.

2 The temperature of the flame determines the color of the flame, the flame is a reaction (violent flame) when the temperature is low, it is infrared, as the temperature rises, the flame changes from red, orange (3000 degrees) to yellow, white (4000 degrees) to cyan blue (5000-6000 degrees) to purple (more than 7000 degrees) to the last invisible ultraviolet rays (tens of thousands of degrees), the color is constantly changing.

From the perspective of high-energy physics, the flames in the infrared and colored spectral bands are all low-energy flames, and the temperature continues to be high, and the color of the flame ranges from ultraviolet rays to X-rays to gamma rays, etc., which are all "colors" that cannot be invisible.

The purple color of the fire has the highest temperature and the hottest.

The solid quality of the flame is a high-temperature gaseous or plasma substance. There are two factors that determine the color of the flame:

1. The color of the flame depends on the temperature of the flame, as the temperature rises, the flame changes from red, orange to yellow, white to cyan blue to purple to the last invisible ultraviolet ray.

2. The elemental composition of gaseous and plasma substances determines the intrinsic spectrum of flames, and each element in the element table will emit its own specific light color at high temperatures, because there are many kinds of elements that are emitting light. This is also the reason why the colors of the various flames are different.
