Name the type of nuclear reaction which is involved in the working of:
a hydrogen bomb.
The 'coolants' which can be used in the reactor of a nuclear power station are:
(a) liquid mercury and nitrogen dioxide
(b) liquid sodium and carbon dioxide
(c) liquid ammonia and carbon monoxide
(d) liquid boron and uranium oxide
The heat energy released during nuclear fission and fusion is due to the:
(a) conversion of stored chemicals into energy
(b) conversion of momentum into energy
(c) conversion of mass into energy
(d) conversion of magnetism into energy
A nuclear reaction is represented by the following equation:
`""_92^235U+_0^1n-> _56^139Ba+_36^94Kr+xc+E`
What type of bomb is based on similar type of reaction?
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.
State, giving reason, whether the following nuclear decay are allowed or not?
\[\ce{_Z^AP -> _{Z-2}^AY + _2^4He}\]
A certain nucleus X has a mass number 14 and atomic number 6. The nucleus X changes to `"_7Y^14` after the loss of a particle. Name the particle emitted.
Complete the following fission reaction:
\[\ce{_92U^235 _0n^1 -> _aSb^133 + _41Co^b + 4_0n_1 + energy}\]
Write down the values of a and b.
An element 92U238 losses one alpha particle, and then one β-particle and then again one β- particle to get the final nucleus bQa.
(i) Write down the values of a and b.
(ii) State the relationship between the nuclei P and Q.
In nuclear power plants, the chain reaction cannot be controlled.
In an atomic power station, nuclear energy is converted into electrical energy.
What are the places in which atomic power stations located in Tamil Nadu?
Which is the process used to harness nuclear energy these days? Explain it briefly.
Give scientific reasons.
It is absolutely necessary to control the fission reaction in nuclear power plants.
Which source of electricity generation is least harmful to the environment?
