None of the products of nuclear fission of uranium are radioactive?
The answer is FALSE. Products of Nuclear fission of Uranium are highly radioactive.
Is it true or false that uranium nuclei split during nuclear fission?
It is true that a uranium nucleus splits in the nuclear fission of uranium.
The cadmium in the control rods slows down a nuclear fission reaction by absorbing neutrons true or false?
True. Cadmium (and boron plus some other elements) absorbs neutrons, thus limiting or slowing the fission chain in a nuclear reactor.
A nuclear reaction in which the nuclei of atoms join together is called nuclear fission.true or false?
False. Combining nuclei to form a new nucleus is called nuclear fusion. Nuclear fission is the splitting of an atomic nucleus.
True or false Nuclear reactions convert matter into energy?
False.Atoms themselves only change during nuclear decay, fusion or fission. Outer electrons can be shared, donated or received during bonding but the atom doesn't change in and of itself.When matter changes state the bonds themselves are not affected. All that happens in a change of state is that molecules gain more kinetic energy. The bonds within the molecules are not altered.
A nuclear reactor produces energy from uncontrolled fission?
False, the fission in nuclear reactors is controlled with the movable control rods.
Is it true or false that the process by which energy is produced in the sun is known as nuclear fission?
false
None of the products of nuclear fission of uranium are radioactive?
The answer is FALSE. Products of Nuclear fission of Uranium are highly radioactive.
Is it true or false that uranium nuclei split during nuclear fission?
It is true that a uranium nucleus splits in the nuclear fission of uranium.
Brakes are to a car as control rods are to a nuclear-fission chain reaction - true or false?
true
A nuclear power plant produces energy through nuclear fission reactions that provide heat to create steam which then powers a turbine and generator that create electricity true or false?
That's true.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
The cadmium in the control rods slows down a nuclear fission reaction by absorbing neutrons true or false?
True. Cadmium (and boron plus some other elements) absorbs neutrons, thus limiting or slowing the fission chain in a nuclear reactor.
Is it true or false atomic bombs work by atomic fisson?
yes, both true & false. They can work either by fission or some combination of fission & fusion. Most modern nuclear bombs use both fission & fusion to optimize for mission, size, weight, cost, etc. Total yield can vary from 100% fission to more than 95% fusion.
When a certain isotope such as Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
Is it True or False that Nuclear Power is not a viable form of useful energy due to your inability to harness it?
Wildly false.
Is this true or false in a controlled nuclear chain reaction the energy released as heat can be used to generate electricity?
It is true. The heat can flash water to steam, which spins turbines, which generates electricity.
