Chapter 40, Problem 43A

To determine

The method in which approximate energy release either in fusion or fission by using the table of nuclear mass and the equation $\Delta E=\Delta m{c}^2$ .

Explanation of Solution

Introduction:

The energy released in the nuclear fission or nuclear fusion is proportional to change in the mass of reactant and product in the reaction. The loss of mass appears as the energy in the reaction.

The release of energy is proportional to the change in the mass in nuclear fission or fusion. The physicist can predict the change in the mass of reactant and product by the release of energy in the nuclear fusion or fission reaction or vice-versa.

Conclusion:

Thus, the physicist can predict the release of energy in nuclear fission or fusion by the change in the mass of reactant and products.
