Nuclear fission involves splitting atomic nuclei of uranium-235 or plutonium-239 when they absorb a neutron, causing the nucleus to split into smaller nuclei along with additional neutrons and energy release. This splitting can trigger a chain reaction where the released neutrons cause further fissions and more energy release.

Nuclear fission
This document discusses nuclear fission and was prepared by a group of students. It provides a brief history of nuclear fission pioneers like Otto Hahn and Enrico Fermi. It defines fission as the splitting of a heavy nucleus into smaller fragments. When uranium-235 captures a neutron, it becomes unstable uranium-236 and splits into fragments, releasing neutrons and energy in the process. This energy release can be harnessed for nuclear power generation or results in an atomic explosion depending on whether the fission reaction is controlled or uncontrolled.
Nuclear Chemistry: Nuclear fission
This document discusses nuclear fission, which involves changes in nuclear composition and releases tremendous energy. Nuclear fission occurs when a large nucleus is bombarded by a small particle, causing the nucleus to split into smaller nuclei and neutrons. Some elements can undergo fission spontaneously, while others require bombardment by neutrons to induce fission. When Uranium-235 is bombarded by a neutron, it forms an unstable Uranium-236 nucleus that undergoes fission, splitting into smaller nuclei like Krypton-91 and Barium-142 along with additional neutrons. A chain reaction can occur when a critical mass of uranium undergoes fission, releasing heat and energy in an atomic explosion. Nuclear power

The document discusses nuclear fission and fusion. Nuclear fission occurs when a nucleus splits into two smaller nuclei and releases neutrons. There are two types of fission: spontaneous fission of unstable radioactive isotopes and induced fission which is caused by bombarding atoms with neutrons.

nuclear power plant
Nuclear power plants generate electricity through a process of nuclear fission. Uranium atoms are mined, enriched, and formed into ceramic pellets that are bundled into fuel rods. When the fuel rods are placed in the reactor, neutrons cause the uranium atoms to split and release heat. This heat is used to boil water into steam which spins turbines that generate electricity. Reactors are designed with multiple safety features like thick concrete and steel containment structures to prevent radiation release.
Nuclear energy
Nuclear energy works through nuclear fission, where uranium-235 is split in a nuclear reactor, generating heat. This heat is used to boil water and create steam that powers generators to produce electricity. Key advantages are that it is an energy-dense source that produces reliable base-load power with low greenhouse gas emissions. Disadvantages include nuclear waste, decommissioning costs, and safety risks from meltdowns. Overall, nuclear energy provides society with cheap, efficient electricity while creating jobs through global interest in the technology.
Nuclear energy
This document discusses nuclear energy and its uses. It describes how nuclear fission and fusion work to produce energy. Nuclear fission splits atoms to release energy, which is used in nuclear power plants. Nuclear fusion joins atoms together and occurs in the sun.

Nuclear energy powerpoint.
Nuclear power plants produce electricity through nuclear fission, which is the splitting of uranium atom nuclei. This releases a large amount of energy that is used to heat water and produce steam that spins turbines to generate electricity. While nuclear energy produces few greenhouse gas emissions, it generates radioactive nuclear waste that is difficult to store and remains dangerous for thousands of years. The economics of nuclear power are impacted by its high capital costs to build plants, but also low fuel costs over the plant's lifetime.
Components of nuclear reactor
A nuclear reactor has several main components:
1. The reactor core contains fuel elements, control rods, coolant, and moderator. It is typically a right circular cylinder 0.5-15 meters in diameter.
2. A reflector surrounds the core to reflect neutrons back into the core.
3. Control rods made of heavy elements like cadmium or lead are used to maintain or stop the nuclear reaction by absorbing neutrons.
4. A moderator like water, heavy water, or graphite is used to slow neutrons to increase the chance of fission.

Aqa physics nuclear fission
There are two fissionable substances, uranium 235 and plutonium 239, commonly used in nuclear reactors. Nuclear fission occurs when these substances absorb a neutron, causing the atomic nucleus to split into two smaller nuclei and release two or three neutrons or energy, with the released neutrons potentially causing a self-sustaining chain reaction.
P1.1.4 heating and insulating buildings
U values measure how effective materials are as insulators, with lower U-values indicating better insulation. The specific heat capacity of a substance is the amount of energy needed to change its temperature by 1 degree Celsius per kilogram, and can be calculated using measurements of a substance's initial and final temperatures, mass, time, current, voltage and power from a practical experiment where it is heated.
Aqa heating and insulating buildings
This document discusses various methods of heating and insulating buildings to reduce energy costs. It explains that U-values measure a material's effectiveness as an insulator, with lower U-values indicating better insulation. Solar panels can heat water from sunlight to heat buildings or provide hot water. The payback time of energy-saving solutions measures cost-effectiveness as the time to recoup initial costs from fuel savings. Examples given include loft and cavity wall insulation, draught excluders, and double glazing.
Projectile motion at an angle
Velocity must be broken down into its x and y components using trigonometric functions like cosine and sine. Excel can be used to model the path of a projectile by taking the equations of motion and rewriting them so that x and y positions are calculated separately over time based on the initial velocity components.
OCR Physics A Scalars and vectors
The document discusses scalars and vectors, including examples of scalar and vector quantities. It also provides examples of calculating resultant forces and velocities from multiple forces and velocities acting at angles, including using scale diagrams, Pythagoras' theorem, and resolving forces into perpendicular components.
Aqa force and motion
Forces and motion are discussed. Key points include:
- Velocity is speed in a stated direction and acceleration is the rate of change of velocity over time.
- A bus accelerates from 5 m/s to 25 m/s in 10s, so its acceleration is 2 m/s2. A lizard accelerates from 8 m/s to 20 m/s in 4s, so its average acceleration is 3 m/s2.
- Acceleration can be calculated from the gradient of a velocity-time graph. The area under a velocity-time graph equals the distance traveled.
Alpha beta and gamma decay equations
This document discusses three types of radioactive decay: alpha, beta, and gamma. Alpha decay involves emitting two protons and two neutrons from the nucleus, represented by helium, which decreases the mass and atomic number by 4 and 2 respectively. Beta decay occurs when an electron is ejected from the nucleus, which changes a neutron to a proton, keeping the mass the same but increasing the atomic number by 1. Gamma decay simply releases excess energy without changing the mass or atomic number.
Atomic structure for AQA GCSE Physics
This presentation discusses atomic structure, including that atoms have a small, central nucleus composed of protons and neutrons which is surrounded by electrons. The nucleus contains positively charged protons and neutral neutrons of similar size, while electrons are much smaller and negatively charged. An atom's number of protons equals its number of electrons, giving it an overall neutral charge, though atoms can gain or lose electrons to form ions. Isotopes are atoms with the same number of protons but different numbers of neutrons.
