Let's look at the weight of so much liquid nitrogen. One liter of liquid nitrogen is 1000 cubic centimeter (cm? ) and the density of liquid nitrogen is 0.8 1g/cm? It is about 8 100000 kg of liquid nitrogen, and the mass of the sun is 2.0? 10 30 kg, so the gap between the two is still quite large. First of all, we can be sure that no amount of liquid nitrogen will put out the sun. Why?
Although we know that liquid nitrogen is very cold and can absorb a lot of heat, and nitrogen is also an inert gas with very stable properties, except for 2 1% oxygen, the remaining 78% is nitrogen. With so much nitrogen, they will not participate in any chemical reaction in life at all, that is, the structure of nucleus and electrons is very stable, and the nucleus of nitrogen is also very stable and will not decay. So on earth, liquid nitrogen can be used to cool everything, which is very safe. It can also be used to put out fires. If a pot of liquid nitrogen is poured on it, anything on fire can't stand it, and it loses its temperature and goes out in an instant.
But the sun is different from any reaction we see on earth. The sun is made up of many different elements and gases, which means that no matter what elements are on the earth, there are also elements in the sun. Only the composition ratio is different, in which 70% is composed of hydrogen, 28% is composed of helium, and other elements such as carbon, nitrogen, oxygen and even heavier elements only account for 1.5% of its composition.
The luminescence and heating of the sun is not a common oxidation reaction on the earth, but the fusion of light elements to heavy elements at its core. The mass lost in each nuclear fusion is E = MC 2 to generate energy and release gamma rays. These gamma rays need to walk 700 thousand kilometers from the core of the sun to reach the photosphere on the surface. As you may remember, the speed of light is very fast, and it only takes two seconds to walk this way.
But in fact, the density inside the sun is extremely high, and every step of photons will collide with charged particles and scatter in random directions, which is called random walking. Therefore, it takes at least 654.38 million+years for photons to escape from the sun's surface from the core. During this collision, photons will also provide a radiation pressure to the sun from the inside out to resist gravity, which is why it is too big to collapse.
This radiation pressure will also slow down the hydrogen fuel outside the core, even until the sun runs out of hydrogen fuel inside the core and starts to burn helium. When it expands into a red giant, there will still be a lot of hydrogen in the outer layer, that is, the sun will not burn its own fuel when it dies. Most of the fuel in the outer layer will not precipitate to the core. After mastering the above knowledge, what will happen if these liquid nitrogen are poured into the sun?
What will happen if we pour nitrogen into the sun?
The surface temperature of the sun is high. At such a high temperature, when liquid nitrogen is poured on the surface of the sun, it will vaporize instantly. 99999999 liters of liquid nitrogen is not enough to cool the surface of the sun in a large scale, and it will only lead to a very large explosion, which may produce a dark spot at a local point on the surface of the sun, which is a cold spot caused by the instantaneous absorption of a large amount of heat by liquid nitrogen. But it won't be long before this area heats up again.
Liquid nitrogen injected into the surface of the sun will be ionized into nitrogen nuclei and electrons by high temperature, and most charged particles may be blown into interstellar space by the solar wind. Only a few nitrogen nuclei will circulate up and down in the troposphere of the sun, but they will never sink to the radiation layer because the sun has strong radiation pressure from the inside out.
What if it's increasing? Pouring liquid nitrogen with the same mass as the sun on the surface of the sun will cause a fatal blow to the sun. Liquid nitrogen with the same solar mass will quickly lower the surface temperature of the sun and put it out for at least several decades. However, because the reaction speed of the sun's core will not stop, after several decades, the heat inside the sun may reheat the surface and ionize the thick nitrogen layer covering the sun. On the contrary, the surface of the sun will emit a large number of charged particles, which will do harm to other planets.
But we don't have to worry, because in the decades when the sun went out, we no longer existed. When the sun shines again, life on earth will return to its original point. Another round of creation will begin.
What happens if a large amount of liquid nitrogen is injected into the core of the sun? During gasification, liquid nitrogen will expand at least 700 times, thus increasing the pressure inside the sun. This may cause the sun to explode. Without the sun, our solar system would collapse and planets would fly in a straight line in the outer space of our solar system.
If the sun is lucky enough to survive and not explode, even if this happens, life on earth will still face problems. A large amount of nitrogen can react with a large amount of hydrogen in sunlight to produce explosive ammonia. In this way, the temperature of the solar thermonuclear reaction will rise, releasing higher energy.
This will increase the heat and brightness of the sun, as well as radiation. The temperature on the earth will rise greatly. The radiation intensity is enough to harm the eyes and skin of any living thing. At high temperature, all the water on the earth begins to evaporate, and the air saturated with water vapor will make it difficult for people with weak cardiopulmonary function to breathe. At the same time, the earth will also be threatened by melting polar glaciers and hurricanes.
So any idea of putting out the sun will have serious consequences. After all, the sun is not a fire on the earth, and nuclear reaction is the most powerful energy in the universe at present.
