The source of energy of stars is nuclear fusion. Fusion reaction occurs at very high temperature, about `10^(7) `. Energy released in the process of fusion is due to mass defect. It is also called `Q`-value. `Q = Delta mc^(2), Delta m =` mass defect.
The binding energy per nucleon of `._(1)H^(2)` and `._(2)He^(4)` are `1.1 MeV` and `7 MeV`, respectively. If two deuteron nuclei react to form a single helium nucleus, then the energy released is
