What is nuclear fusion?

• The process of splitting a heavy nucleus into two lighter nuclei.

• The process of combining two light atomic nuclei to form a heavier nucleus.

• The removal of neutrons from an atomic nucleus.

• The addition of protons to an atomic nucleus.

Which condition is essential for nuclear fusion to occur?

• Low temperature

• High pressure

• High temperature

• Low pressure

What element is commonly used as fuel in nuclear fusion reactions?

• Uranium

• Hydrogen

• Lead

• Carbon

In the Sun, hydrogen nuclei fuse to form which element?

• Helium

• Lithium

• Beryllium

• Neon

What is the primary energy output form of nuclear fusion in the Sun?

• Kinetic energy

• Thermal energy

• Electromagnetic radiation

• Sound waves

Which of the following is a challenge in achieving controlled nuclear fusion on Earth?

• Obtaining sufficient amounts of fusion fuel

• Containing the high-energy plasma

• Generating initial fusion reactions

• All of the above

What role do magnetic fields play in controlled nuclear fusion reactors?

• They initiate the fusion reaction.

• They confine and control the plasma.

• They cool down the reactor.

• They extract energy from the plasma.

Which fusion reaction pathway is primarily responsible for energy production in stars heavier than the Sun?

• Proton-proton chain

• CNO cycle

• Triple-alpha process

• Beta decay

What is the net result of the proton-proton chain reaction in terms of nuclear particles?

• 4 protons are converted into 1 helium nucleus, 2 positrons, and 2 neutrinos.

• 2 protons are converted into 2 helium nuclei.

• 4 protons are converted into 2 helium nuclei and 4 electrons.

• 2 protons are converted into 1 helium nucleus and 2 electrons.

Why is helium-3 considered a valuable resource for future nuclear fusion reactors?

• It is abundant on Earth.

• It produces more energy than other isotopes when fused.

• It results in a cleaner fusion process with fewer radioactive byproducts.

• It is easier to handle and store than other isotopes.
