Nuclear Fission | MCQs

Explanation

The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

• Fission is the splitting of a nucleus that releases free neutrons and lighter nuclei.
• The fission of heavy elements is highly exothermic which releases about 200 million eV compared to burning coal which only gives a few eV.

Explanation

Nuclear fission is a process in which a heavy, unstable nucleus splits into two or more smaller nuclei, releasing energy and often additional particles like neutrons.

This process is the opposite of nuclear fusion, where smaller nuclei combine to form a heavier nucleus.

Explanation

Nuclear energy is the energy released from the nucleus of an atom, either through fission (splitting of atoms) or fusion (combination of atoms).

This energy is released in the form of heat and radiation, and is harnessed in nuclear power plants to generate electricity.

Key Points:

• Solar energy is energy from the sun
• Geothermal energy is energy from the Earth's internal heat
• Tidal energy is energy from ocean tides
