Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.
