MCQ
The phenomenon of radioactivity is
  • A
    Exothermic change which increases or decreases with temperature
  • B
    Increases on applied pressure
  • Nuclear process does not depend on external factors
  • D
    None of the above

Answer

Correct option: C.
Nuclear process does not depend on external factors
c
(c) Radioactivity is natural phenomenon in which particles are emitted from nuclei as a result of nuclear instability and does not depend upon external factors. Because the nucleus experiences the intense conflict between the two strongest forces in nature, there are many nuclear isotopes which are unstable and emit some kind of radiation.
