Chapter 24, Problem 67A

Interpretation Introduction

Interpretation:

The current limitations of fusion as a power source to be described.

Concept introduction:

Reaction of nuclear fusion that is responsible for making heaviest elements, able to release massive quantities of energy.

Answer to Problem 67A

As a power source nuclear fusion are economical.

Explanation of Solution

Nuclear fusion takes large amount of electricity that maintained the magnetic field essential to certain a fusion reaction. In 20^th century electricity of nuclear fusion is very expensive. Thus as a power source nuclear fusion are economical. It leaves little toxic waste. Fusion needs extremely high energies to initiate a sustain reaction.

Conclusion

Combination of atomic nuclei is nuclear fusion. To initiate a sustain reaction fusion needs extremely high energies.
