Nuclear Physics Test - Fission Vs Fusion
-
Fission means to
-
Break apart
-
Put together
-
To fizz out
-
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or smaller, lighter nuclei. Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

Which reaction do nuclear power plants use because it is easier to accomplish?
Explanation
Nuclear power plants use fission reactions because they are easier to accomplish. Fission involves the splitting of atomic nuclei, releasing a large amount of energy. This process is relatively easier to control and sustain compared to fusion reactions, which involve the merging of atomic nuclei. Fusion reactions require extremely high temperatures and pressures, making them more challenging to achieve and maintain in a controlled manner. Therefore, fission is the preferred reaction for generating power in nuclear power plants.Rate this question:

Takes two small nuclei and combines them into a larger nucleus
Explanation
Fusion refers to the process of combining two small nuclei into a larger nucleus. This process releases a tremendous amount of energy and is the same process that powers the sun and other stars. In fusion reactions, the nuclei must overcome their mutual electrostatic repulsion to come close enough for the strong nuclear force to bind them together. This process is responsible for the immense energy produced in nuclear fusion reactions and is being researched as a potential source of clean and sustainable energy on Earth.Rate this question:

Is this a picture of FISSION or FUSION?
Explanation
Based on the given question and answer, it can be inferred that the picture is related to fission. Fission refers to the splitting of an atomic nucleus into two or more smaller nuclei, accompanied by the release of a large amount of energy. This process is typically associated with nuclear power plants and atomic bombs. Therefore, the correct answer is fission.Rate this question:

What are the benefits of fission and fusion?
-
They both release large amounts of energy
-
They both absorb large amounts of energy
-
They both are easy to use
Correct Answer
A. They both release large amounts of energyExplanation
Fission and fusion both release large amounts of energy. In fission, the nucleus of an atom is split into two smaller nuclei, releasing a significant amount of energy in the process. In fusion, two smaller atomic nuclei combine to form a larger nucleus, again releasing a substantial amount of energy. Both processes have the potential to generate vast amounts of energy, which can be harnessed for various purposes such as generating electricity.Rate this question:

What is required to make fusion reactions to work?
-
High temperature
-
Pressure
-
Low temperature
-
Single neutron hitting the nucleus
Correct Answer(s)
A. High temperature
A. PressureExplanation
Fusion reactions require both high temperature and pressure to work. The high temperature is necessary to overcome the electrostatic repulsion between the positively charged nuclei, allowing them to come close enough for the strong nuclear force to bind them together. The pressure is needed to confine the plasma and maintain the high temperature required for the fusion reactions to occur. Without these conditions, fusion reactions cannot take place.Rate this question:

What is a disadvantage of fission?
-
The products are radioactive
-
The products cause fires
-
The products cause combustion reactions
Correct Answer
A. The products are radioactiveExplanation
A disadvantage of fission is that the products generated during the process are radioactive. This means that they emit radiation, which can be harmful to living organisms and the environment. Radioactive materials require careful handling, storage, and disposal to prevent any potential health risks and contamination.Rate this question:

-
Is cleaner than FUSION
-
Requires a single neutron to start the reaction
-
Requires lots of heat and pressure
-
The splitting of atom
-
The combining of atoms
-
Produces radioactive wastes when reaction is over
Correct Answer(s)
A. Releases large amounts of energy
A. Is simpler than FUSION
A. Requires a single neutron to start the reaction
A. The splitting of atom
A. Produces radioactive wastes when reaction is overExplanation
Fission is a nuclear reaction that involves the splitting of an atom, which releases large amounts of energy. It is simpler than fusion because it does not require the high temperatures and pressures needed for fusion reactions. Fission reactions require a single neutron to start the reaction, and they produce radioactive wastes when the reaction is over.Rate this question:

Is this a picture of FISSION or FUSION?
Correct Answer(s)
fusionExplanation
This picture is likely a representation of fusion because fusion refers to the process of combining two or more atomic nuclei to form a heavier nucleus. In fusion, a large amount of energy is released, which can be seen in the picture. Fission, on the other hand, involves the splitting of a heavy nucleus into two or more lighter nuclei. However, without the actual picture or more context, it is difficult to provide a definitive explanation.Rate this question:

Choose all the places where fusion occurs naturally?
-
Sun
-
Nuclear power plants
-
Lighting
-
In fires
Correct Answer
A. SunExplanation
Fusion occurs naturally in the sun. In the core of the sun, extremely high temperatures and pressures cause hydrogen atoms to collide and fuse together to form helium. This process releases a tremendous amount of energy in the form of light and heat. Fusion reactions are also artificially created in nuclear power plants, but they do not occur naturally in lighting or fires.Rate this question:
