3:36 PM Thu 28 Apr < то (b) Nuclear fusion is regarded as the ultimate power source due to the huge amount of energy released during this process. The sun is a highly efficient nuclear reactor in which a "He nucleus can be produced out of four ¹H atoms. The diagram below shows the binding energy per nucleon for a range of atoms. 10₂ To Fe Sn fission He H 50 100 150 200 250 Number of nucleons, A (mass number) Using the graph above, calculate the approximate binding energy in joules for an oxygen atom ¹50? (5 marks) (ii) U can undergo nuclear fission by splitting into Rb and Cs each with a binding energy per nucleon of 8.4 MeV. Calculate the energy released in MeV, when one atom of 2 (binding energy per nucleon of 7.6 MeV) undergoes nuclear fission as described. Where does this energy come from? (4 marks) When four ¹H atoms fuse together to create a 'He nucleus, 7.07 MeV per nucleon of energy is released. One gram of 5 contains approximately 2.56 x 10²¹ atoms and one gram of ³H contains 6.02 x 10" atoms. Using this information and your answer to (b)(i), show that fusion releases nearly 10 times as much energy as fission. (4 marks) He Binding energy per nucleon (MV) fusion-> 58% 1 +: 0
