Energy given out by the sun is due to nuclear fusion.

(a) Draw the plot of binding energy per nucleon (BE/A) as a function of mass number A. Write two important conclusions that can be drawn regarding the nature of nuclear force. (b) Use this graph to explain the relase of energy in both the processes of nuclear fusion and fission. (c) Write the basic nuclear process of neutron undergoing beta -decay. Why is the detection of neutrinos found very difficult?

Give two example of nuclear fusion.

(a) What is nuclear fusion ? Give one example and write its nuclear reaction. (b) What other name is given to nuclear fusion ? Give reason.

Which of the following statements is not true about nuclear energy generation in a nuclear reactor? (A) Energy is obtained by a process called nuclear fission. (B) The nucleus of Uranium is bombarded with high energy neutrons. (C) A chain reaction is set in the process. (D) In this process a tremendous amount of energy is released at a controlled rate.

Which of the following equations, pick out the possible nuclear fusion reactions?

From the following equation pick out the possible nuclear fusion reactions

Using the curve for the binding energy per nucleon as a function of mass number A, state clearly how the release in energy in the processes of nuclear fission and nuclear fusion can be explained.

What do you understand by the term nuclear fusion ?

Why a huge amount of energy is released in nuclear fission of nuclear fusion solution.

The percentage efficiency of nuclear fissiion is higher than nuclear fusion.
