The enormous amount of energy released in an explosion of an atomic bomb is due to the - (1) conversion of mass into energy (2) conversion of chemical energy into heat energy (3) conversion of mechnical energy into nuclear energy (4) conversion of neutrons into protons

1 Answer

Answer :

(4) conversion of neutrons into protons Explanation: The enormous amount of energy released in an explosion of an atomic bomb is due to the converson of neutrons into protons. When, a neutron strikes the nucleus of an atom of the isotopes uranium 235 or plutonium 239, it causes that nucleus to split into two fragmens, each of which is a nucleus with about half the protons and neutrons of the original nucleus.
