Nuclear Fission starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Nuclear Fission.
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 nuclear reactor produces 3.6 × 109 J of energy per second. How much mass is converted to energy per second? (Use c = 3.0 × 108 m/s)
A sample of Uranium-235 undergoes fission and releases 2.5 × 1010 J of energy. How many fission events occurred? (Each fission releases 200 MeV; 1 eV = 1.6 × 10-19 J)
Calculate the energy released when 0.001 kg of mass is lost during nuclear fission. (Use E = mc2, c = 3.0 × 108 m/s)
Describe the difference between nuclear fission and nuclear fusion.
Describe the function of a coolant in a nuclear fission reactor.
Describe the role of neutrons in a nuclear fission chain reaction.
Explain the environmental impact of nuclear fission power plants.
Explain why a critical mass is necessary for a sustained nuclear fission chain reaction.
Explain why nuclear fission is considered a non-renewable energy source.
Explain why Uranium-238 is not suitable as a primary fuel for most nuclear reactors.
