Question

The nuclear fuel in the sun is___________.

Answer 1

Hint:The energy of the Sun is gained by the temperature of an exploding hydrogen bomb. It is done by changing hydrogen to helium.

Complete step by step answer:
We know that,
The type of nuclear reaction taking place in the core of the Sun is known as nuclear fusion and involves hydrogen nuclei combining 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.Now,with the enormous gravity of that much mass, its hydrogen is packed together at incredible pressure as it approaches the core of the star, and pressure causes the gas to heat to 100 million degrees Kelvin.Therefore,the nuclear fuel in the sun is hydrogen gas. The sun can be considered as a big thermonuclear furnace where hydrogen atoms continuously get fused into helium atoms. Mass gets lost during these fusion reactions and energy is being produced.
Now the reaction is as follows,
\[4{}_1^1H \to {}_2^4He + 2{}_{ + 1}^0e + \vartriangle \]
Where, represents a tremendous amount of energy.
 Additional information:
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.

Note:Students must not get confused by nuclear fusion and nuclear fission both are different.The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
