What else can I help you with?
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.
None of the products of nuclear fission of uranium are radioactive?
This statement is incorrect. The products of nuclear fission of uranium are typically highly radioactive, including elements such as cesium, strontium, and iodine. These radioactive byproducts require proper handling and disposal to prevent harm to human health and the environment.
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. The process by which energy is produced in the sun is known as nuclear fusion, not fission. Nuclear fusion is the process in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process.
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.
Is this true or false in a controlled nuclear chain reaction the energy released as heat can be used to generate electricity?
True. In a controlled nuclear chain reaction, the energy released as heat can be used to generate electricity through a process called nuclear fission. By controlling the rate of reactions and capturing the heat produced, nuclear power plants are able to generate electricity efficiently and safely.
A nuclear reaction in which the nuclei of atoms join together is called fission true or false?
False. A nuclear reaction in which the nuclei of atoms join together is called fusion, not fission. Fusion is the process that powers the sun and hydrogen bombs. Fission, on the other hand, is when the nucleus of an atom is split into two or more smaller nuclei.
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?
True. Nuclear power plants use nuclear fission reactions to generate heat, which then creates steam. This steam drives a turbine connected to a generator that produces electricity.
When a certain isotope such as Pa-231 is hit by a neutron it will always split into the same smaller nuclei?
false
None of the products of nuclear fission of uranium are radioactive?
This statement is incorrect. The products of nuclear fission of uranium are typically highly radioactive, including elements such as cesium, strontium, and iodine. These radioactive byproducts require proper handling and disposal to prevent harm to human health and the environment.
Brakes are to a car as control rods are to a nuclear-fission chain reaction - true or false?
True. Brakes control the speed of a car by reducing its kinetic energy, while control rods in a nuclear reactor control the rate of fission reactions by absorbing neutrons and reducing the chain reaction. Both mechanisms are essential for safely managing the system.
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
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.
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.
