[单选题]
Which of the followitzyqai4.8 r+aoy,vl. ng a,( z5 jhwt;focorrectly shows the change in total binding energy per nucleon in nuclear fissiona , owz5hf;t(j and nuclear fusion?
A. Nuclear fission is increases ; Nuclear fusion is increases
B. Nuclear fission is decreases ; Nuclear fusion is increases
C. Nuclear fission is decreases ; Nuclear fusion is decreases
D. Nuclear fission is increases ; Nuclear fusion is decreases
参考答案: A
本题详细解析:
Explanation: Energy is released in both nuclear fission and nuclear fusion. Hence the total nuclear mass in both cases decreases, which corresponds to greater mass defect and greater binding energy per nucleon.
