Question

Research into nuclear fusion will likely require a large investment of time and money before it might be used as an energy source. Which statement best describes the benefits that would make the investment worthwhile?

Answer 1

Answer: B) Fusion produces large amounts of energy, and the fuel is found on Earth.

Explanation:

These are the statments that accompany the question:

A) Fusion requires a large amount of energy and occurs in stars.

B) Fusion produces large amounts of energy, and the fuel is found on Earth.

C) Fusion produces no radioactive waste, and the fuel is plentiful.

1D) Fusion requires little energy to begin and would continue through a chain reaction.

Answer:

Nuclear fusion is the union of smaller atom nuclei to form one bigger and more stable nucleous.

The nuclear fusion  reactions are able to release vast amounts of energy.

The energy of the Sun comes from the nuclear fusion of hydrogen atoms, H, to form, helium atoms, He.

The research into nuclear fusion is justified becasue there is plenty fuel (low atomic mass atoms like hydrogen) and the huge ability to release energy.

Also, generally, the products of the fusion reaction are not radioactive. But this is a general rule, not a 100% condition.

Therefore, although the reduction of radioactive waste is a plus, the complete justification is given by the option: B) Fusion produces large amounts of energy, and the fuel is found on Earth.
