State whether the fission of uranium-235 is caused by low energy neutrons or high energy neutrons.

Which product of the nuclear fission of uranium-235 is utilised to cause further fission of its nuclei ?

The energy of thermal neutrons is

For a chain nuclear fission of U^(235) the moderation of neutron is a must because very high energy neutron

Which of the following statements is not true about nuclear energy generation in a nuclear reactor? (A) Energy is obtained by a process called nuclear fission. (B) The nucleus of Uranium is bombarded with high energy neutrons. (C) A chain reaction is set in the process. (D) In this process a tremendous amount of energy is released at a controlled rate.

Which particles bring about the fission of uranium-235 ?

Assertion:There occurs a chain reaction when uranium is bombarded with slow neutrons. Reason:When uranium is bombarded with slow neutrons more neutrons are produced

The product of the fission of U^(235) by thermal neutron are

When a uranium isotope U is bombarded with a neutron, it generates kr three neutrons

Which of the following is correct regarding nuclear fission? (i) The process in which a heavy nucleus is broken into two nearly equal fragments, is called ‘Nuclear Fission’ (ii) Nautral uranium has two istopes, ._(92)U^(238) and ._(92)U^(235) in the ratio 1 : 0.07 . the fission of U^(235) takes place only by fats neutrons, whereast that of U^(235) is possible by slow neutrons (iii) One of the reaction for fission of U^(235) ._(92)^(236)U+._(0)^(1)nrarr._(92)^(236)Urarr._(52)^(144)Ba+._(36)^(89)Kr+3_(0)^(1)n + energy (iv) In the fission of one U^(235) nucleus, about 200MeV of enegry of obtained. Most of this enegry is obtained from of K.E. of fragments obtained by fission, the rest of obained as K.E. of emitted neutrons, gamma -rays, heat and light radiation
