Differentiate between nuclear fission and fusion.
Assertion (A) : Nuclear fission reactions are responsible for energy generation in the Sun. Reason (R) : Light nuclei fuse together in the nuclear fission reactions.
Draw a diagram to show the variation of binding energy per nucleon with mass number for different nuclei and mention its two features. Why do lighter nuclei usually undergo nuclear fusion ?
Distinguish between nuclear fission and fusion giving an example of each.
Explain the release of energy in nuclear fission and fusion on the basis of binding energy per nucleon curve.
Calculate the energy released in MeV in the following reaction: ²₁H + ³₁H → ⁴₂He + n Given: m(²₁H) = 2.014102 u m(³₁H) = 3.016049 u m(⁴₂He) = 4.002603 u mₙ = 1.008665 u
