What words can be extinguished with two matches?

The words that can be extinguished with two matches are, two, ten, eight, people, entering the factory. If it is a number, you can put it out, 1, 7. If it is a letter, it can be released, T, L, J, X, V, R. If the match can be folded, it can display more Chinese characters, numbers, letters, force, knife, 4, Y, N, K, F, U.

Introduction to the competition

Matches are a kindling tool which is ignited by friction based on the principle that objects generate heat by friction, using the chemical activity of strong oxidants and reducers.

/kloc-in the second half of the 0/8th century, yellow phosphorus was mainly used as an igniter. Because yellow phosphorus is toxic, it is gradually replaced by phosphorus sulfide matches. Although the latter is non-toxic, it may spontaneously ignite at any time, which is very unsafe. 1855, the match factory established in Sweden in the world successfully developed safety matches, which were gradually adopted by all countries in the world.

Today's matchbox is coated with red phosphorus, antimony trisulfide and glass powder. The substances on the matchhead are generally KClO3, MnO2, S, etc. When the two sides rub, the heat generated by the friction makes the red phosphorus in contact with KClO3 and other substances ignite, and the combustible materials on the matchstick burn, thus causing the matchstick to catch fire.

The advantage of safety matches is that red phosphorus is non-toxic, attached to the side of matchbox and matchstick respectively, with oxidant, and does not touch each other when not in use. That's why it's called a safety race.
