Question

Which of the following statements is true?

A. Nuclear fusion involves the splitting of a nucleus; nuclear fission involves combining two or more nuclei.
B. Reactors for nuclear fusion are much more realistic than are reactors for nuclear fission.
C. Nuclear fusion produces much more energy than nuclear fission.
D. Nuclear fusion requires a enough fissionable material present to create and sustain a chain reaction

Answer 1

The answer is C. Nuclear fusion produces much more energy that nuclear fission. However, the problem is that nuclear fusion requires unrealistically high temperatures to create.

Answer 2

Step-by-step explanation:

Let us consider each statement.

A. Nuclear fusion involves the splitting of a nucleus; nuclear fission involves combining two or more nuclei.

False: Nuclear fusion involves combining two or more nuclei and nuclear fission involves the splitting of a nucleus.

B. Reactors for nuclear fusion are much more realistic than are reactors for nuclear fission.

False: both the reactors are realistic.

C. Nuclear fusion produces much more energy than nuclear fission.

True: the energy of fusion is more than the energy of nuclear fission.

D. Nuclear fusion requires a enough fissionable material present to create and sustain a chain reaction

False: Nuclear fission requires a enough fissionable material present to create and sustain a chain reaction.
