Video transcript

The fission of uranium-235 releases approximately 200 MeV (million electron volts) of energy per nucleus. This translates to about 3.2 x 10^-11 joules. This substantial energy release is what makes nuclear power and weapons extremely potent.

Questions and answers

  1. What is uranium-235 fission?

    Uranium-235 fission is the process where the uranium-235 nucleus splits into smaller parts, releasing a large amount of energy.

  2. How much energy is released during uranium-235 fission?

    Approximately 200 million electron volts (MeV) of energy is released per uranium-235 nucleus when it undergoes fission.

  3. Why is uranium-235 used in nuclear power and weapons?

    Because uranium-235 fission releases a substantial amount of energy, it is used as a fuel in nuclear reactors and as a core material in nuclear weapons.

  4. How is the energy from uranium-235 fission measured?

    The energy released is commonly measured in million electron volts (MeV) or joules per nucleus.
