1a Describe how thermal energy is obtained byfission, specifically when a U=235 atom is hit by a slow-motionneutron (less than 0.9 MeV). When one states that 200 MeV of energyare released by a fission event, what is the form of thisenergy?
1b. The energy released by fission is by thechange in mass and Einstein’s equation (E=Δmc2). If themass of one uranium 235 atom is 235.042924 amu and the mass offission products is 234.92754 amu, determine the energy in Joulesand MeV released by one fission. (Note: 1 amu = 1.66 x10-27kg and 1 ev = 1.6 \x 10-19J).
1c. For an atom, the atomic number is thenumber of protons, while the atomic weight (i.e. molecular weight)can be 235 or 238 depending on the isotope. Determine the number ofatomic particles (electrons, neutrons, and protons) for U-235,U-238, Kr-90. Note: The atomic number of Krypton is 36.
