Questions and answers

  1. What is nuclear fission?

    Nuclear fission is the process by which the nucleus of a heavy atom, such as uranium-235, splits into smaller parts, releasing a significant amount of energy.

  2. How much energy does uranium-235 release during fission?

    The fission of 1 gram of uranium-235 releases approximately 83.14 trillion joules of energy.

  3. Why is uranium-235 used in nuclear reactors?

    Uranium-235 is used because it readily undergoes fission, releasing a large amount of energy that can be harnessed for electricity generation.
