Nuclear Energy: Nuclear Binding Energy, Fission, and Fusion. Einstein discovered that matter could be converted to energy (and vice-versa). The equation that expresses this mass-energy equivalency is: E = mc2 (c = 3.00x108 m/s) or E = ( m)c2. Every process that releases energy is accompanied by an equivalent loss of mass.

The energy released by the combustion of the fuse wire, e1, is determined using Equation 3.(8) Finally, it is also required that the transfer of heat between the calorimeter and the environment is determined. During the warm up and stabilization period, heat can be lost from the calorimeter to the surroundings. Equation 4 determines the corrected
