Hello, today you will learn FUN FACTS ABOUT IRON! In the Russian Empire, for several centuries, Yekaterinburg was the leader in the amount of mined iron. The roof of the parliament in Great Britain is made of iron ore mined in Yekaterinburg. When iron is heated to a temperature of two thousand eight hundred and sixty-two degrees Celsius, it turns into a vaporous state. In turn, this metal becomes liquid when heated to one thousand five hundred and thirty-eight degrees. In the very first time after the technology of extraction and processing of iron became available to mankind, it surpassed the price of gold in value. In ancient times, before the metallurgical industry appeared, human tribes made weapons and tools from iron nuggets they found. Which often had a meteoric origin. The color of blood in the human body is due to the red blood cells in it, which carry oxygen. The color of the bodies, in turn, is precisely red because of the iron that is part of them. In molluscs, on the other hand, the blood cells include copper, which is why their blood has a blue tint. The content of iron in the earth's crust of our planet is approximately four point sixty-five hundredths of a percent of its total mass. In outer space, the number of iron meteorites prevails over the number of stone ones. An adult's body contains approximately five grams of iron. Of the foods consumed by humans, apples, pomegranates, chocolate, some plants of the legume family, as well as beef and pork liver can boast the highest iron content. With a lack of iron in the body, a person experiences drowsiness, apathy, hair loss and brittle nails. If we hypothetically deprive the human body of all the iron in it, it will not live even a few minutes. Since all organs and tissues will no longer receive oxygen, which is extremely necessary for vital activity, in the transportation of which throughout the body, iron plays a decisive role. In the Middle Ages in Europe, only very noble people had the privilege of wearing iron jewelry. Although, even without paying attention to the ban, the middle class could not afford it due to the high cost of such jewelry. Iron ore, from which iron is mined, contains a lot of impurities of various minerals. There are on average about three hundred of them in the ore. The largest piece of iron found on earth was the remnant of a meteorite that fell on the African continent in Numibia. The weight of what was left of the space guest was sixty-six tons. Iron is destroyed by the action of certain acids, in particular, this metal is completely dissolved in sulfuric and nitric acids. The weight of iron, which is extracted from the bowels of the earth every forty-six minutes, is equal to the weight of all the gold mined by mankind to this day. Iron oxidizes on contact with oxygen to form an oxide of this metal called rust. When carbon is alloyed with iron, both cast iron and steel are formed. It is noteworthy that the difference in the amount of carbon in these alloys varies from three to five percent. The basis for the manufacture of both electrical and conventional magnets is iron. In terms of its prevalence in the earth's crust, iron is second only to aluminum. Despite the fact that often a lot of impurities are observed in iron ores, there are still places on our planet where deposits of native pure iron are found. In particular, there are such deposits in Greenland. The finest dust, consisting of finely dispersed iron, has the ability to ignite spontaneously. Due to exposure to oxygen, it can easily flare up. According to the scientific community, the Earth's core is under tremendous pressure and heated to very high temperatures. Because of what the iron, of which it is composed, is in a molten state. Different isotopes of iron have different half-lives. Moreover, the difference between the lifetimes of these isotopes is incredibly huge and varies from ten minutes to two million six hundred years. In seawater, iron is less than in river water in the range from a hundred to a thousand times. If the information was useful to you, you can like and subscribe to the channel! See you soon.
