Statement-1 : Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.Statement-2 : For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z

This question contains Statement −1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.Statement - I:Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. andStatement - IIFor heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decrease with increasing Z.Statement −1 is false, Statement −2 is true.Statement - 1is true, Statement −2 is true; Statement −2 is correct explanation for Statement-1.Statement −1 is true, Statement −2 is true; Statement −2 is not a correct explanation for Statement-1.Statement −1 is true, Statement −2 is False.

Multiple Choice QuestionWhich statement describes the process of nuclear fusion?Multiple choice question.Small nuclei join to form a larger nucleus.Large nuclei split into smaller nuclei.A nucleus emits alpha or beta particles, creating a new nucleus.Electrons from inner energy levels of the atom are captured by the nucleus.

Nucleus A is having mass number 220 and its binding energy per nucleon is 5.6 MeV. It splits in two fragments ‘B’ and ‘C’ of mass numbers 104 and 116. The binding energy of nucleons in ‘B’ and ‘C’ is 6.4 MeV per nucleon. The energy Q released per fission will be:

Question 131 ptsWhich occurs in a fusion reaction between two atoms?Group of answer choicesEnergy is absorbed as a less stable element forms.A new element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of the atoms are split apart and energy is released. Flag question: Question 14Question 141 ptsIn what way are nuclear fission and nuclear fusion similar?Group of answer choicesBoth processes involve the decay of nuclei of atoms.Both processes result in formation of one or more new elements.Both processes are currently used to generate electrical energy.Both processes occur naturally inside the core of a star.
