In general, matches cannot be lit underwater, but matches can be vaporized in water.
ignited, and at the same time some black technology.
It is possible to throw a lit match into the water and the match will not be extinguished.
To get back to the point, to know if matches can be lit in water, we need to first understand why matches burn.
The principle of burning of general matches is:Due to the match head in thePotassium chlorateand tetraphosphorus trisulfide, which generates heat when rubbed against other objects with rougher surfaces, such as the sides of matchboxes or sandpaperBecause potassium chlorate and phosphorus trisulfide do not have very high ignition points, they do not require much effort to light a match.
From here we can see that to light a match,It must be produced to be able to achieve potassium chlorate and tetraphosphorus trisulfideIgnition pointtemperature
Let's take a look at what is necessary for a fire to burn.
In general, there are three necessary conditions for fire to burn: first.
1. Combustibles; Clause.
2. Reach the ignition point of combustibles; Clause.
3. Adequate oxygen.
In the case of combustibles, after several tests, I found that a damp match can barely be lit with a lighter, and although there is no open flame, there is smoke coming out, and if the match is immersed in water, it is impossible to light an ordinary match anyway. As for the stormproof matches, which are said to be using black technology, according to the explanation, the matches are indeed not extinguished after the lit matches are immersed in water, but the unlit matches cannot be lit until they are dried. This is unattainable.
Looking at the second point, the ignition point of potassium chlorate and tetraphosphorus trisulfide is not very high, but it is still unknown whether they can ignite normally if they are soaked in water. Due to the presence of boiling water and water vapor, this is barely possible.
Theoretically, water is composed of hydrogen and oxygen, and it does contain a lot of oxygen, but because it is too difficult to separate these two substances, this condition can only be regarded as unattainable.
In this way, two of the three conditions necessary for burning a match in water cannot be met, and one can barely be met. Therefore, matches cannot be lit underwater.
-
Matches cannot be lit under water because they are already soaked under the fire, so they cannot be ignited. Wet matches are not usually lit, let alone matches in water.
-
Matches cannot be lit in water, and they need to be lit with the help of some substances contained in the air. In addition, matches contain phosphorus, which can get wet when it comes into contact with water.
-
No. The main component of matches is phosphorus, and phosphorus will be damp underwater, which will have a certain effect on it and cannot be ignited normally.
-
No. Because match lighting requires the involvement of air, and there is no air underwater, it is not possible to light a match underwater.

Can matches be lit underwater? The guy tested it himself, and he was stunned after reading it!
-
Matches can be ignited because they have a relatively low ignition point, i.e. they can be ignited at low temperatures (generally 32 43). The head of a match is made of substances such as monoammonium phosphate, potassium oxide, etc., while the match stick is made of a wooden material and a binder. When we rub the match head or other rough objects on the matchbox vigorously, due to the heat brought by the friction and the rough surface caused by the friction, the flammable substances such as monoammonium phosphate and potassium oxide in the head can be more prone to chemical reactions, so as to emit sparks and ignite the fuel gas (usually liquid paraffin) attached to the match head, and finally make the whole match burn.
It should be noted that although matches seem to be simple, they may also cause fires, so they need to comply with safety regulations and keep them properly to avoid danger when using them.
-
Match heads are mainly composed of oxidants, flammables, and adhesives. The side of the matchbox is mainly composed of red phosphorus parasen, diantimony trisulfide, and binder. When a match is struck, the match head rubs against the side of the matchbox to generate heat, and the heat released causes the oxidant to decompose, producing a small amount of oxygen and making the red phosphorus glow.
This causes the flammable material on the head of the match to burn, so that the match can be lit.
Early matches were made of white phosphorus, which is prone to spontaneous combustion when heated, which is very dangerous. Moreover, white phosphorus is poisonous, and the workers who make matches will be poisoned to death if they are not careful. Later, in 1852, after the improvement of the Swedes from Tastronum, safety matches were invented, which greatly reduced the danger of matches.

Scientific principle: 1. The outer wall of the glass bottle is an arc that protrudes outward, when the glass bottle is filled with water, it is equivalent to a convex lens, and the water ignition match is the principle of using the convex lens to gather the light in the focus, and the sunlight is gathered to a point, so that the temperature reaches the red phosphorus on the match head, and the match is ignited.
2. The substance of the match head has red phosphorus, which is dissolved in water to generate phosphoric acid and releases a large amount of hot bands, and the heat reaches the ignition point of red phosphorus, which will ignite the match.
-
Can a match be lit in water? Foreigners and side experiments tested, and after reading it, I refreshed my blind knowledge! Lack of sheds.
-
Matches cannot be lit in the water, and they need to be lit with the help of some substances contained in the air. Moreover, matches contain phosphorus, which will be damp when it encounters water.

The burning temperature of diamonds in the air is about 1000.
The maximum temperature of the match is 1400 degrees, but it is only temporary, even a small drill bright stone can not make the temperature of the whole diamond reach 1000 degrees, so the match is not ignited diamond!
As long as the water is clean enough to open your eyes, it is better not to do so and you should wear swimming goggles.

The ignition point is 75 degrees Celsius. >>>More
Impossible, in fact, even if Jupiter's atmosphere could be ignited, it would not become a star, and the star does not rely on burning air, but on nuclear fusion inside.
