Nuclear energy is produced in much the same way that electricity is produced by other power plants; the splitting of atoms creates heat, turning water into steam, and then the pressure of the steam turns the generator with the end product being electricity. The process of splitting atoms is known as nuclear fission, and it is nuclear fission that replaces the fossil fuels of coal, natural gas or oil that are normally used to produce electricity in traditional power plants.Know More
In a nuclear power plant, nuclear energy is created when a nuclear reactor creates heat. The heat is used for making steam. The steam is used to turn a turbine that is connected to a generator, which is essentially an electromagnet. The generator produces electricity that is then routed to customers' homes.
Uranium is the type of fuel that is used in nuclear fission. Inside pellets of uranium fuel reside millions of uranium nuclei that are split during nuclear fission. This splitting sets off the release of a huge amount of energy; most of it is from kinetic energy, but some is from radiation. The kinetic energy produces the heat inside the nuclear reactor that produces steam and in the end, electrical power.Learn more in Motion & Mechanics
Steam power works on the principle that heating water to the point of vaporization causes a build-up of pressure, because the vaporized water takes up more space than liquid water. Gases, liquids and solids are all held together by different molecular forces.Full Answer >
Water has a low vapor pressure due to the strong intermolecular forces between its molecules. The type of chemical bonding between water molecules is referred to as hydrogen bonding.Full Answer >
A pressure gauge allows a fluid to enter from the item or equipment being measured and reacts by moving a calibrated rod inside it. The pressure can be correctly read when the rod has moved to its maximum position.Full Answer >
The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object's kinetic energy. This principle of work and its relationship to kinetic energy is a core mechanical physics concept.Full Answer >
