Nuclear Fusion
Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fusion is the energy source of the sun and stars.
Fusion Bomb
A fusion bomb is also known as a thermonuclear bomb or hydrogen bomb which releases a large amount of explosive energy during a nuclear chain reaction when the lighter nuclei in it, combine to form heavier nuclei, and a large amount of radiation is released. It is an uncontrolled, self-sustaining nuclear chain reaction where isotopes of hydrogen combine under very high temperature to form helium. They work on the principle of operation of atomic fusion. The isotopes of Hydrogen are deuterium and tritium, where they combine their masses and have greater mass than the product nuclei, get heated at high temperatures, and releases energy.

Question 17
Which example BEST demonstrates the conversion of nuclear energy into electrical energy?
|
A |
Friction of water molecules in a cloud causes a large buildup of electrons in one area. When the voltage is large enough, a lightning bolt occurs. |
|
|
B |
In a hydro-electric dam, a large amount of water molecules flows downward from a water reservoir, turning turbines that generate electricity. |
|
|
C |
A fully charged battery is attached to a closed electrical circuit, causing electrons to flow through the circuit. |
|
|
D |
A reactor generates heat by splitting uranium, creating steam that turns turbines to generate electricity. |
As we know, energy can be transferred from one form to other. We are able to transfer nuclear energy into electrical energy also. Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
