Question

Which of the following is incorrect about the nuclear fission reaction?

Options

• It occurs in nuclei with mass number A > 230.

• It occurs at normal temperature.

• It can be controlled to sustain.

• It occurs at a temperature of the order of 107 K and a very high pressure.

Answer 1

It occurs at a temperature of the order of 107 K and a very high pressure.

Explanation:

Fission happens easily at normal temperatures. Extremely high temperature and pressure are required for nuclear fusion, not fission.
