In this article, the most interesting facts about such a key element in our lives as hydrogen.
1. Hydrogen is the lightest and most common chemical element in our universe, which, incidentally, It consists of three quarters of its mass.
2. It turns out hydrogen-powered cars fuel, do not emit harmful exhaust gases, their products Activities are only water vapor and hot air. First in the world model that runs on hydrogen is Toyota Mirai four-door sedan.
3. Hydrogen fuel cells generate electricity. A byproduct of their chemical reaction is water, while it is so clean that the american astronauts on space shuttle, consume it regularly. Meanwhile liquid hydrogen is used as rocket fuel to remove satellites and other spacecraft into orbit of the Earth and beyond limits.
4. It turned out that the existence of life on Earth also depends on hydrogen that the sun produces. Thanks to the reactions of this element, helium is formed in the core of our native star, generating with a staggering amount of solar energy.
5. Today, many manufacturers are working to ensure that when help automobile hydrogen fuel fuel our homes electricity during a power outage or other emergency situations.
6. Since hydrogen is 14 times lighter than air, if you fill it with balloons, they will move away from the Earth at a speed of 85 km in an hour that is twice the speed of helium-filled balls, and six times the speed of balls filled with natural gas.
7. Hydrogen can become liquid, but for this to happen, it temperature must be lowered to -423 degrees Fahrenheit (-252.78 degrees Celsius). For this reason, in large in quantities it is usually stored under pressure in the form gas.
