State whether the fission of uranium-235 is caused by low energy neutrons or high energy neutrons.
The fission of uranium-235 is caused by low-energy neutrons, which are also known as slow-moving neutrons.
Explanation
The fission of uranium-235 is caused by low-energy neutrons (or, slow-moving neutrons) because slowing the neutron, the possibilities of the neutron reacting with the nucleus of Uranium-235 increases significantly, allowing the chain reaction to be maintained.
Nuclear fission - It is defined as the splitting of a heavy nucleus into two lighter or daughter nuclei through a nuclear reaction. The heavy nucleus is bombarded with neutrons, which results in the production of a high amount of energy.
