Question 2

Both nuclear fusion and nuclear fission reactions

Revolt · Accepted Answer

release large amounts of energy.

Question 3

Which best describes nuclear fission?

Revolt · Accepted Answer

A nucleus collides with a neutron and splits, releasing energy.

Question 4

Which statement is true about nuclear fusion?

Revolt · Accepted Answer

It produces nearly all the elements that are heavier than helium.

Question 5

Which is a characteristic of nuclear fusion?

Revolt · Accepted Answer

involves the collision of two nuclei

Question 6

How does critical mass play a role in nuclear reactions?

Revolt · Accepted Answer

It is the minimum amount of material needed to sustain a fission reaction.

Question 7

Which is a characteristic of nuclear fusion but NOT nuclear fission?

Revolt · Accepted Answer

is the energy source of stars

Question 8

Which type of reaction does this diagram represent?

Revolt · Accepted Answer

nuclear fission because an atom is splitting into two large fragments of comparable mass

Question 9

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?

Revolt · Accepted Answer

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

Question 10

Which is most likely why many scientists reject the cold fusion theory?

Revolt · Accepted Answer

The original results have not been replicated consistently and reliably.
