A certain mass of hydrogen is changed to helium

Asked by admin @ 13/08/2021 in Science viewed by 286 People

A certain mass of Hydrogen is changed to Helium by the process of fusion. The mass defect in fusion reaction is 0.02866 u. The energy liberated per u is – (Given 1 u = 931 MeV)

Answered by admin @ 13/08/2021

The energy associated with 1u =931MeV

Hence energy liberated = 0.02866X931MeV= 26.7 MeV

As _{1}^{2}\textrm{H}+_{1}^{2}\textrm{H}\rightarrow _{2}^{4}\textrm{He}

\therefore Energy liberated per unit = \frac{26.7}{4}MeV

=6.675 MeV
