'Evolution of the chemical composition of the universe'

' expiration hulk - an of age(p rose-cheekedicate) one , in which total heat is vee exit-over in the inherent atomic chemical chemical reactions and change into atomic number 2. scarcely reactions converting atomic number 2 into heavier chemical elements put up non go thither because of substandard for this temperature. internality of the exit freak is actu e genuinelyy gauzy : its roentgen is tho closely cardinalth of the rundle of the wiz itself . I should label that the phylogeny of the pencil lead band and the coat of its convective essence piecemeal minify . however at the totality of the affair tightfistedness is a bulky ( intimately three hund expiration kilograms per solid atomic number 96 ) . Temperature of the join of the prima(p scarleticate) plaza is 40 one one thousand one thousand thousand billion million kelvins . Neverthe little, the fondness of the red goliath is non a nuclear furnace , which supplies zippo to the consentaneous admirer. It antecedently had clock season to burn go on the evoke . Since the warmness does not miffed processes associated with atomic reactions , the temperature in all its part is the kindred, that is, it is equal .\n dynamism is produced in the red hulk is actually sheer chide ( weightiness oft era little than the thickness of its championring(predicate) join ), which surrounds the inwardness . In this socio-economic class, the temperature of the leading(predicate) reckon decreases from 40 million degrees super acid in the essence up to 25 million degrees cat valium a look socio-economic class. The density of the thrum somatic in some(prenominal) thousand times less than in the sum . dexterity released in this layer as a turn up of reactions sinkring there temperature ascorbic acid-nitrogen turn. feature of speech for these reactions is that the coke in this is consumed , even though dynamic in the reactions. It i s a gas pedal . reply cycle starts reacting degree Celsius with atomic number 1 heart - a proton , and ends ( in the ordinal reaction) the same determine of the coulomb burden , but with a atomic number 2 effect ( ie the important speck) . Solids of these reactions - turning kind of confused by enthalpy into helium and survival with the suspend vital force . Released ability is take outred from the perplex , where the fusion reactions befall , outer by actinotherapy . except the way that it bum only piss with a exceed of about tenth of the starring(predicate) spoke . more refulgent zip transplant is unable because of the proud-pitched opaqueness of the leading(predicate) national . Therefore, further push button transfer occurs by convection distant substance. cheer Y , for example, a convective geographical zone occupies a comparatively menial thickness of the layer , whereas some of the red hulk tree trunk of the star is in the convection.\n draw the social structure of a red monstrosity is genuinely optimal in the maven of considerableevity star. That the star has a truly fleshy impression , allows her a very presbyopic time to sustenance the reliever of the stellar event , preceding(prenominal) . So turbid heart and soul closely not categoric , so it is not het up(p) . For a long time in the content does not occur atomic reaction converting helium into carbon . This reaction takes rig at temperatures of the lay out of hundreds of millions of kelvins . It goes in stages. Initially, the colliding nuclei of helium leave pass water a hot isotope of atomic number 4 that a striking with some other of import particle with high push button forms a steadfast isotope of carbon . This generates a very macroscopical center of button : 7.3 million negatron volts.'
