Nuclear Fusion Quiz

What is nuclear fusion?

• The splitting of a large nucleus into smaller nuclei

• The joining of two lighter nuclei to form a larger nucleus

• The process of converting energy into mass

• The decay of radioactive elements

Which elements are involved in the example of nuclear fusion given in the video?

• Two helium nuclei

• One hydrogen and one helium nucleus

• Two hydrogen nuclei

• Two carbon nuclei

Why does nuclear fusion release a large amount of energy?

• Because the new nucleus is heavier than the original nuclei

• Because energy is transferred to the new nucleus

• Because some of the mass is converted to energy

• Because of the high temperatures involved

What equation is used to calculate the energy produced in nuclear fusion?

• E = mc^2

• E = m/c^2

• E = mc

• E = m^2c

What is the value of the speed of light squared used in the energy calculation?

• 9 x 10^20

• 9 x 10^12

• 9 x 10^16

• 9 x 10^8

What is one major advantage of nuclear fusion?

• It doesn't produce any radioactive waste

• It can be done at room temperature

• It requires very low pressure

• It produces a lot of radioactive waste

What is a significant challenge in achieving nuclear fusion on Earth?

• Generating enough electricity

• Producing enough radioactive waste

• Finding enough hydrogen

• Achieving the required high temperatures and pressures

Where does nuclear fusion naturally occur?

• In the Earth's core

• Inside stars

• In nuclear reactors on Earth

• In the atmosphere

What is nuclear fission?

• The fusion of two helium nuclei

• The joining of two lighter nuclei to form a larger nucleus

• The splitting of a large unstable nucleus into smaller nuclei

• The process of converting energy into mass

Which process is currently used on Earth to generate electricity?

• Solar power

• Nuclear fusion

• Nuclear fission

• Chemical reactions
