Describe the steps that occur in the process of fission.
answer
Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and more neutrons. The neutrons hit the nuclei of more atoms, splitting them and releasing more energy and neutrons.
question
What are the products of a fusion reaction? Check all that apply.
answer
2, 3, & 4
energy
heavier atoms
a neutron
question
Complete this equation that represents the process of nuclear fission.
answer
A: 146
B: 56
question
Complete this equation that represents the process of nuclear fusion.
answer
A: 222
B: 86
question
Which statement accurately describes mass-energy equivalence?
answer
A. It includes the idea that mass is a measure of the energy within an object.
question
Explain why nuclear fission and nuclear fusion release large amounts of energy.
answer
In nuclear fission, the mass of the original nucleus is greater than the mass of the products. The extra mass is converted to energy. In nuclear fusion, the total binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus. Extra energy is released during the reaction.
question
What is the energy equivalent of an object with a mass of 1.83 kg?
answer
A. 1.65 × 1017 J
question
A power plant needs to slow down the fission reactions in its nuclear reactor. In which direction should the uranium-containing rods in the diagram be moved?
answer
D. down
question
Why is nuclear energy able to be used for practical purposes?
answer
A. The reactions are controlled to regulate energy output.
