What kind of reactions occur between the gases that make up stars? Where the star is a giant ball of glowing gas at a very high temperature, and carbon dioxide and H2, i.e. hydrogen gas, are the most common molecules in interstellar gas clouds, and stars vary in size, temperature and age, but most of them consist of the same elements and behave According to the same principles, what kind of interactions occur between the gases that make up stars? This we will answer later.
How are stars formed?
Stars form within relatively dense concentrations of interstellar gas and dust known as molecular clouds. These regions are very cold, that is, the temperature ranges from 10 to 20 degrees Kelvin, just above absolute zero. At these temperatures, gases become intermolecular, which means that atoms fuse together. Extreme cold also causes gas to clump to high densities, and when the density reaches a certain point, stars are formed, and star formation begins when the denser parts of the cloud core collapse under their weight, that is, due to their gravity and mass. The size of the star’s nuclei usually reaches about 104 solar masses for each form of gas and dust, and the nuclei are denser than the outer cloud, so they collapse first, and when the nuclei collapse, they fragment into blocks of about 0.1 parsec in size. Mass from 10 to 50 solar masses, then these masses are formed into protostars to form the protostar.
What type of reactions occur between the gases that make up stars
Stars are made up mostly of hydrogen and helium, and they are so densely packed into the star that the pressure in the center of the star is great enough to start nuclear fusion reactions. So the interactions that occur between the gases that make up the stars are nuclear fusion reactions, where in the nuclear fusion reaction the nuclei of two atoms unite to form a new atom, and the most common thing in the heart of the star is that two hydrogen atoms merge to become a helium atom Although nuclear fusion reactions require a lot of energy to start and form a new star, once they start producing huge amounts of energy in the star, the energy generated by fusion reactions in the center of the star is pushed outward to balance the internal gravity, and this energy also moves outward Through the star’s layers until finally reaching the star’s outer surface, the star’s outer layer glows brightly, sending energy out into space as electromagnetic radiation including visible light, heat, ultraviolet light, and radio waves.
Facts about stars
After learning about the type of reactions that occur between the gases that make up stars, it’s important to know a few facts about stars and how they form:
Stable stars such as the Sun maintain homeostasis by producing energy through nuclear fusion in their cores, determining the star’s fusion energy generation capacity. Every second in the Sun approximately 600 million tons of hydrogen undergo fusion into helium, with about 4 million tons being converted into energy in the process, and this rate of hydrogen use means that the Sun (and all other stars) will eventually run out of central fuel. . Stars come in various masses ranging from 1/12 solar mass (MSun) to approximately 100-200 MSun, and there are much more low mass than high mass stars. The most massive stars (spectral type O) are also the most luminous and have the highest surface temperatures, while the least massive main sequence stars (spectral type M or L) are the least luminous and coolest. A galaxy of stars like the Milky Way contains huge amounts of gas and dust which is enough to create billions of stars like the sun. In the event that you want to find stars that are still in the process of formation, it is best to look in places that have a lot of raw materials from which stars are collected, because stars are made of gas, so the most important interest of star explorers is in dense and cold clouds gases and dust in the Milky Way.
At the end of this article, we summarize the most important points in it, where they were identified What kind of reactions occur between the gases that make up stars? And how stars are formed, plus facts about stars and their formation.
