High school physics chapter 22 section 4. How do hydrogen atoms interact with each other normally versus in the sun s core. However the sun s core is so hot and pressurized that it increases their speed causing them to bump into each other and undergo nuclear fusion.
E mc 2. Mass in the form of hydrogen atoms is converted to energy as described by einstein s formula. This is the principle fusion reaction in the sun.
The sun s structure and nuclear fusion the proton proton chain. 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 products is manifested as either the release or absorption of energy this difference in mass arises due to the difference in atomic binding energy between the atomic nuclei. Using nuclear fusion to produce energy and its pros and cons.
What nuclear fusion is and how and where it occurs. The hydrogen and helium atoms that constitute sun combine in a heavy amount every second to generate a stable and a nearly inexhaustible source of energy. Nuclear fusion is the source of sun s phenomenal energy output.
Nuclear fusion in the sun explained perfectly by science. New zealand born sir ernest rutherford 1871 1937 and associates demonstrate nuclear fission splitting the atom and nuclear fusion in a long series of ingenious physics experiments which gradually reveal the structure of the atomic nucleus. A brief history of nuclear fusion.
The sun is composed of 74 percent hydrogen measured by mass an element having a nucleus consisting of a single proton. The binding energy of helium is the energy source of the sun and of most stars. It is estimated that the sun releases 3 8 10 26 joules of energy every second.
Complete fusion of all these hydrogen nuclei would release about 17 200 000 000 000 joules j of energy.
Sun nuclear fusion diagram. The energy from the sun both heat and light energy originates from a nuclear fusion process that is occurring inside the core of the sun the specific type of fusion that occurs inside of the sun is known as proton proton fusion. Inside the sun this process begins with protons which is simply a lone hydrogen nucleus and through a series of steps these protons fuse together and are.
