The following question are about the nuclear reactor of a power plant.
Which isotope of uranium produces the energy in the fuel rods?
Calculate the energy released in joules when 5 g of a material is completely converted into energy doing a nuclear reaction.
The energy in the reactor of a nuclear power station is produced by the process of:
(a) nuclear diffusion
(b) nuclear fission
(c) nuclear fusion
(d) nuclear fermentation
A nuclear reaction is represented by the equation:
`""_1^2H+_1^2H->_2^3He+xc+E`
Identify the particle c and the number x of such particles produced in the reaction.
Which of the following statements are correct?
Neutrons have
Two statements are given - one labelled Assertion (A) and the other labelled Reason (R).
Assertion (A): In the process of nuclear fission, the amount of nuclear energy generated by the fission of an atom of uranium is so tremendous that it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
Reason (R): The nucleus of a heavy atom such as uranium, when bombarded with low energy neutrons, splits apart into lighter nuclei. The mass difference between the original nucleus and the product nuclei gets converted to tremendous energy.
