The two false statements about nuclear fusion are:
b. nuclear fusion is used to generate electricity at nuclear power plants
c. the fuel for nuclear fusion is often uranium
Explanation:
- Statement a is true; nuclear fusion primarily occurs in the cores of stars, including our Sun.
- Statement b is false because nuclear power plants typically use nuclear fission (the splitting of atomic nuclei, usually uranium or plutonium) to generate electricity, not fusion.
- Statement c is false because the common fuels for nuclear fusion include isotopes of hydrogen, such as deuterium and tritium, rather than uranium.
- Statement d is true; nuclear fusion releases large amounts of energy, which is one of the reasons it is studied as a potential power source.
