Question

Assuming that the splitting of a U²³⁵ nucleus liberates the energy of 200 MeV, find: 

(a) the energy liberated in the fission of one kilogram of U²³⁵ isotope, and the mass of coal with calorific value of 30 kJ/g which is equivalent to that for one kg of U²³⁵; 

(b) the mass of U²³⁵ isotope split during the explosion of the atomic bomb with 30 kt trotyl equivalent if the calorific value of trotyl is 4.1 kJ/g.

Answer 1

(a) the energy liberated in the fission of 1 kg of U²³⁵ is

The mass of coal with equivalent calorific value is
