AIIMS Full Mock Test 1 - Question 30
In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A):Energy output in a fusion reaction is very much less than energy released in the fission process.
Reason(R):Fusion is a weaker energy-source than fission.
Detailed Solution for AIIMS Full Mock Test 1 - Question 30
The energy output in a fusion reaction (21.6 MeV) is very much less than the energy released in the fission of a U235 nucleus (190 MeV). But this does not mean that fusion is a weaker energy source than fission. The number of hydrogen nuclei in 1 gram of heavy hydrogen is much larger than the number of U235 nuclei in 1 gram of uranium. Therefore, the energy obtained by the fusion of a certain mass of heavy hydrogen is much larger than tje energy obtained by the fission of equal mass of uranium
