WebThe sun fuses hydrogen into helium. At some point there is not enough hydrogen left, then the sun gets first cooler and starts shrinking. That shrinking increases pressure and temperature. At some point the suns core is hot enough to fuse helium into carbon. The helium to carbon fusion is pretty unstable and will make the sun explode in a ... WebAnswer (1 of 5): Good question. The power from the Sun is 1362 Watts/m2 at 1 AU distance. 1 AU=149.6 billion meters. That means a sphere or ball with that radius has an area of 4*pi*r^2 = 2.812*10^23 square meters. At 1362 Watts/m2 that’s 3.83*10^26 Watts = the power output of the Sun. Four p...

WebShort answer: It's a reaction that actually has multiple steps, but the gist is that the protons turn into neutrons, and emit a positron (anti-electron) and a neutrino in the process. Long answer: The overwhelming majority of matter in the universe is hydrogen-1 which is basically lone protons. This hydrogen gas, in big clouds, condenses to form stars which … WebNov 11, 2024 · And helium-3/helium-4 fusion into two helium-4s accounts for 3% of the reactions by number, releasing 19.99 MeV of energy for each reaction: 10.8% of the Sun’s … The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second. The fusion of lighter elements in stars releases energy and the mass that … See more Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and … See more The release of energy with the fusion of light elements is due to the interplay of two opposing forces: the nuclear force, a manifestation of the strong interaction, which holds protons … See more A substantial energy barrier of electrostatic forces must be overcome before fusion can occur. At large distances, two naked nuclei repel one another because of the repulsive electrostatic force between their positively charged protons. … See more The key problem in achieving thermonuclear fusion is how to confine the hot plasma. Due to the high temperature, the plasma cannot be in direct contact with any solid material, so it has to be located in a vacuum. Also, high temperatures imply … See more In 1920, Arthur Eddington suggested hydrogen–helium fusion could be the primary source of stellar energy. Quantum tunneling was … See more An important fusion process is the stellar nucleosynthesis that powers stars, including the Sun. In the 20th century, it was recognized that … See more Thermonuclear fusion Thermonuclear fusion is the process of atomic nuclei combining or “fusing” using high temperatures to drive them close enough together for this to become possible. Such temperatures cause the matter to become a See more buy cheap vinyl fence orlando
