The energy released by fission of one U^(235) atom is 200 MeV. Calculate the energy released in kWh, when one gram of uranium undergoes fission.

Why a huge amount of energy is released in nuclear fission of nuclear fusion solution.

What is the source of energy in nuclear fission and fusion ?

The ._(92)^(235)U absorbs a slow neutron (thermal neutron) & undergoes a fission represented by (i) The energy release E per fission. (ii) The energy release when 1g of ._(92)^(236)U undergoes complete fission. Given : ._(92)^(235)U = 235.1175 am u (atom), ._(56)^(141)Ba = 140.9577 am u (atom), ._(36)^(92)Kr = 91.9264 am u (atom), ._(0)^(1)n = 1.00898 am u .
