Exploring Nuclear Reactions and Energy

What is the equation that represents the relationship between mass and energy in nuclear reactions?

Which of the following describes a nuclear fission reaction?

• Two light nuclei combine to form a heavier nucleus.

• A heavy nucleus splits into two lighter nuclei.

• A neutron is absorbed by a nucleus, causing it to become unstable.

• A nucleus emits a beta particle.

In a nuclear fusion reaction, what is required to contain the high-temperature plasma?

• Gravitational fields

• Magnetic fields

• Electric fields

• Strong nuclear force

What is the primary challenge in achieving nuclear fusion on Earth?

• Obtaining sufficient quantities of uranium

• Containing the high-temperature plasma

• Preventing radioactive decay

• Cooling the reaction

Which of the following is an example of a radioactive decay process?

• Fusion of hydrogen nuclei

• Splitting of uranium-235

• Emission of an alpha particle

• Absorption of a neutron

What is the unit of energy commonly used in nuclear physics?

• Joule

• Calorie

• Electronvolt

• Watt

• Speed of sound

• Speed of light

• Speed of a neutron

• Speed of an electron

What is the 'mass loss' in a nuclear reaction?

• The mass of the reactants minus the mass of the products

• The mass of the products minus the mass of the reactants

• The energy released in the reaction

• The energy required to start the reaction

Which of the following is a characteristic of induced nuclear fission?

• It occurs spontaneously without external influence.

• It requires the absorption of a neutron.

• It involves the emission of a gamma ray.

• It results in the formation of a single heavier nucleus.

What is the primary fuel used in nuclear fusion reactions in stars?

• Helium

• Uranium

• Hydrogen
