BIG ENCYCLOPEDIA FOR CHILDREN AND ADULTS
When did man start using gas? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? When did man start using gas? A person can receive gas from natural deposits or produce it. Here is an example of how you can get gas. If a clay pipe is filled with coal powder and closed on one side and then heated, smoke will come out of the other end of the pipe. Soon the smoke will stop coming. If fire is brought to the end of the tube, the gas escaping from there will ignite with a bright and even flame. If you increase the scale of this experiment by a thousand times, then you will get an industrial process for making gas from coal. In 1792 artificial gas was first used by Scottish engineer William Murdoch. He purified the gas from the burning coal and put it through pipes to light his house. A few years later, he applied the same system to lighting a factory in Birmingham. In the United States, artificial gas was used for lighting before natural gas was used. In 1812, David Melville of Newport, Rhode Island, lit up his house and the street in front of it with coal gas. In 1816 artificial gas began to light the streets of Baltimore, Maryland. Natural gas was first used in 1821 in Fredonia, New York. Currently, natural gas is used more. This happens because new gas fields have been discovered, new gas technologies have been developed, and new gas pipelines have been built, which allow delivering gas from remote fields to large cities. Author: Likum A. Random interesting fact from the Great Encyclopedia: How did some children's games come about? Nowadays, hide-and-seek is played for fun. But hide and seek appeared a long time ago, when this game had a completely different meaning for the people who played it. Adults usually played hide-and-seek. In some places in England there was a custom according to which, when spring came, people went out into the woods and fields to find there flowers and birds that appeared with the onset of this season. Then what was found was brought to the village so that everyone could see that spring had really come. The search for these signs of spring, which were hiding in the forests, was the beginning of the game of hide and seek. And despite the fact that a lot of time has passed since the appearance of the game, in some countries, even in our time, the one who hides sometimes imitates the cry of a bird. It is interesting that almost all children's games did not begin as games, but from some historical event or from a legend that people believed in. Sometimes some joyful events served as the beginning for them, sometimes sad ones. "London Bridge is falling" is a game that came into being under very serious circumstances. It doesn't even have anything to do with London! It refers to those times when people believed that after death people had to cross some kind of bridge. Some got on the golden bridge to heaven, while others had to go on the old, rickety bridge to meet the devil. This game is played all over the world, each country has its own name!
