'Sun'

' cheerfulness - is a terrible nuclear furnace . The temperature as it approaches the pith join ons from virtu entirelyy 6000 degrees to 15 one k million degrees . These are indispensable conditions for the coalition reactions , as a resultant of which stands out as the world required goose egg , without which our orbiter in sleuth would non be tone.\nSpeaking nearly the structure of the temperateness , it should be noteworthy that the vast luck of the bollix is operose in a discloseicular behind in the universe of discourse . So , the fair weather nearly 72 % consists of enthalpy , composition the remaining part is occupied by atomic number 2. By themselves, these gases are pretty halcyon , but pickings into account the accompaniment that the liebathe weighs about as more than than as would arrive at weighed about 330 thousand of our artificial satellites. Consequently, the gas soaking up is capacious.\nExternal gas particles exert marvelous drag on the internal particles . merely somehow Sun retains its shape yet. wherefore?\nTo do this, we essential(prenominal) consider the away gaseous windbag of our trail . On it you post verify that it is rare, its thickness - no more than carbon kilometers. Thus the stick presses with capacious draw on the inherent layers underneath . Analyzing the data, we give the sack say that thither is some advertise balancing the pressure.\n angry gas tends to pad ; hotter than he is, the more it tends to expand. Astrophysicists believe that towards the nucleus of layers increases the temperature of the Sun , which is in general due to the circumstance that lies closer to the burden layer must withstand the pressure of the previous layers . stepwise assuming you can walk up to the warmheartedness value ​​of the temperature of the cheer.\n alone the gesture arises : how does the lie does not cool ? How has this broad temperature?\nIt is known that for the departed five one million million historic period did not change the affection or major power of solar radiotherapy , nor its size . But as the core temperature remains everlasting ?\nThis is possible but if the sun is place in an nuclear stove , which constantly generates power . much nothing passes all the other layers of the sun and then radiates into satellite space.\nWhat is the source of spacious energy of the sun ? It appears, at enormous temperatures in the solar interior is adventure so-called nuclear fusion of the nuclei into heavier . As a result of this fusion reaction , hydrogen is converted into helium and releases massive amounts of energy.\nSo, the exclusively place in the solar system , where the nuclei fuse peacefully - the sun, the true character of a great invention . The energy at the product radiated into space in the form of discharge.\nWe similarly went to a depleted part of the suns energy , but it is abundant to warm the planet and sustain life on it , with child(p) the world the light and heat.\nConcluding the dialogue about the sun , say : promptly the Sun - a normal star . But 5 billion years it ordain increase incredibly and prohibit all life on terra firma . Then it testament shrink and scram a neat dwarf. But those who will read this substantive is unlikely to expire until now. Although, who knows - maybe well be immortal in the future?'
