In which process does a heavy nucleus split into two lighter nuclei?
freezing
condensation
fission
fusion
What occurs in both fusion and fission reactions?
Small amounts of energy are converted into large amounts of matter.
Small amounts of matter are converted into large amounts of energy.
Heavy nuclei are split into lighter nuclei.
Light nuclei are combined into heavier nuclei.
What is one benefit associated with a nuclear fission reaction?
The products are not radioactive.
Stable isotopes are used as reactants.
There is no chance of biological exposure.
A large amount of energy is produced.
In which type of reaction do two lighter nuclei combine to form one heavier nucleus?
combustion
oxidation
nuclear fission
nuclear fusion
Nuclear fusion differs from nucleus fission because nucleus fusion reactions
form heavier isotopes from lighter isotopes
form lighter isotopes from heavier isotopes
convert mass to energy
convert energy to mass
Which phrase describes a risk associated with producing energy in a nuclear power plant?
depletion of atmospheric hydrogen
depletion of atmospheric carbon dioxide
production of wastes needing long-term storage
production of wastes that cool surrounding water supplies
Which reaction represents fusion?
Which reaction represents fission?
This is an example of...
Chain reaction
Fusion reaction

What would be the advantage(s) of using nuclear fusion to produce energy?
no radioactive waste and more energy produced
safer
requires less regulation
more controlled energy produced, less radioactive waste produced
