Video transcript

When two moles of uranium-235 undergo nuclear fission, approximately 3.24 x 10^10 kilojoules of energy is released. This is because each fission of one uranium-235 nucleus releases around 200 MeV of energy, leading to tremendous amounts of power being liberated, exemplifying the potency of nuclear reactions.

Questions and answers

  1. What is nuclear fission of uranium-235?

    Nuclear fission of uranium-235 is a process where the uranium nucleus splits into smaller nuclei when struck by a neutron, releasing massive amounts of energy.

  2. How much energy is released per fission event of uranium-235?

    Each fission event of a uranium-235 nucleus releases about 200 MeV (million electron volts) of energy.

  3. Why does two moles of uranium-235 release so much energy?

    Because one mole contains Avogadro’s number of atoms, two moles means a vast number of fissions, cumulatively releasing approximately 3.24 x 10^10 kilojoules of energy.

  4. What are practical applications of uranium-235 energy release?

    The energy released from uranium-235 fission is harnessed in nuclear power plants for electricity generation and in nuclear weapons.
