Nuclear fusion reaction is possible in the sun. How?
1 Answer
For nuclear fusion , there needs to be large amount of hydrogen, tremendous amount of heat and enormous pressure which are present inside the sun so nuclear fusion reaction is possible in the sun.
The Sun shines because it is able to convert energy from gravity into light. ... This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion.The steps are:
- Two protons within the Sun fuse. ...
- A third proton collides with the formed deuterium. ...
- Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogen.
The type of nuclear reaction taking place in the core of the Sun is known as nuclear fusion and involves hydrogen nuclei combining together to form helium. In the process, a small amount of mass (just under one per cent) is released as energy, and this makes its way to the Sun's surface before beaming out into space.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.
