As these rough surfaces come into contact with each other they repel. When two atoms are brought very close together they store potential energy. When they move apart that energy becomes kinetic. did nacho appear in breaking badWebThe heat generation rate in a nuclear core is directly proportional to the fission rate of the fuel and the thermal neutron flux present.
