QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Nuclear Fusion.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A fusion reaction releases 3.5 MeV of energy per reaction. How much energy is released by 1.0 × 1020 such reactions? (1 eV = 1.6 × 10-19 J)
Calculate the energy released when 0.001 kg of mass is converted to energy during a fusion reaction. (Use c = 3.0 × 108 m/s)
Describe one major challenge in achieving controlled nuclear fusion on Earth.
Describe the main steps of the proton-proton chain reaction in the Sun.
Describe the role of plasma in nuclear fusion reactors.
Describe the role of the strong nuclear force in nuclear fusion.
Explain why deuterium and tritium are often chosen as fusion fuels in experimental reactors.
Explain why extremely high temperatures are required for nuclear fusion to occur.
Explain why nuclear fusion does not occur naturally on Earth’s surface.
Explain why nuclear fusion is considered a potential solution to the world’s energy problems.
Explain why the mass of the products in a fusion reaction is less than the mass of the reactants.
In a fusion reaction, if the total mass of the products is 0.002 kg less than the mass of the reactants, how much energy is released? (Use c = 3.0 × 108 m/s)
State the equation for the fusion of deuterium and tritium.
