Nuclear fusion is the phenomenon of combining or fusing two or more lighter nuclei to form a more stable heavy nucleus with the liberation of vast amounts of energy.
A huge amount of energy is required for the fusion of nuclei.High temperature(millions of degrees)and high pressure(millions of pascals)are needed to bring about fusion.
Examples
(1)Two deuterons can join together to form a Helium-3 nucleus and a neutron.the nuclear reaction can be represented as
Where C is velocity of light in vacuum.
This famous equation was derived by Albert Einstein in 1905.

Such nuclear reactions are the source of energy in the sum other stars.
The source of energy in both nuclear fusion and nuclear fission is the same,i.e,disappearance of a certain mass in the process which appears in the form of energy. the sum of masses of the products is somewhat less than the sum of the masses of the reactants.This difference in masses before and after the nuclear reaction is called the mass defect(,m).It is this mass defect which appears in the form of nuclear energy according to Einstein's mass-energy relation:E= mc²
Where C is velocity of light in vacuum.
This famous equation was derived by Albert Einstein in 1905.
