    Nuclear fission is either a radioactive decay or a nuclear reaction process in which the nucleus of the atom splits into smaller parts. The fission often produces neutrons and photons and releases a very large amount of energy. Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat which is most likely to be used in steam turbines to produce electricity in a nuclear power station. A nuclear reactor produces and controls the release of energy from splitting the

    The first introduction to nuclear energy was in 1938 when German scientists Otto Hahn and Fritz Strassman, along with Lise Meitner, discovered they could split the nucleus of a uranium atom. This process was later known as fission. In 1942, Italian physicist Enrico Fermi and several other physicists made another discovery regarding nuclear fission. They discovered that the fission of a Uranium atom gave off more neutrons; which could then be split into other Uranium atoms, thus starting a self sustaining

    A nuclear reactor had exploded due to poorly trained workers and a badly executed monitoring procedure. It took over 600,000 emergency workers and firefighters to end the madness. By the end, 63,000 square miles of land were impacted and could not be used for crops. At least 5 million people were sick or disabled, and 985,000 were left dead. Even today, 4.5 million people have their houses on affected land, and are eating food that has been poisoned by this incident. The damage that nuclear power

    greatest factors in world events, it is unsurprising to see nuclear energy, the bridge between fossil fuels and renewable resources, argued for and against so fiercely. Yet under this umbrella term of “nuclear energy” that people enjoy throwing around, there are two wildly different forms of energy. Things that perhaps shouldn’t be lumped together so haphazardly. Those are Nuclear Fission and Nuclear Fusion. In contrast to their similar names, fission and fusion aren’t quite so similar. They differ in many

    When the nuclei of Uranium-235 and Plutonium-239 undergo nuclear fission, they produce waste as a by-product, which is known as nuclear waste or “fission fragments”. (Leslie Corrice, 2015) This waste contains radioisotopes, which are radioactive isotopes that have long half-lives. This means that the radioisotopes are able to stay in the atmosphere for hundreds of thousands of years, which is extremely hazardous to the earth’s environment. Very commonly this waste contaminates water and ruins the

    Nuclear Fission is a process that was discovered by German scientists, Otto Hahn, and his assistant Fritz Strassman on December 17, 1938. Nuclear Fission is a process in which the nucleus of an atom splits into smaller parts. This will release free photons and neutrons, and releases a large amount of energy. If this energy is controlled, it can be used for nuclear energy for nuclear power plants. On the contrary, this process can be used uncontrollably in atomic bombs, such as the ones dropped in

    the energy sources like fossil fuels works against the environment. Nuclear fission is one of the alternative energy sources which is considered to be the future energy source of the world, but just like any other things nuclear fission has several disadvantages and advantages, but it is our responsibility as a society to weigh those implications and come up with a solution which supports the world for the better. Nuclear fission is one of the things which still remains to have an uncertain future

    development of nuclear fission, the pinnacle of which was the successful Trinity Test in 1945. As time went on the technology was improved upon, resulting in nuclear power plants and more powerful weapons. Still, there was a desire for a more efficient, less dangerous, and more powerful means of extracting energy from matter. This desire was met with nuclear fusion. Fusion and fission power differ in a number of significant ways, despite both being based on the concept of nuclear binding energy

    Richard Heck is a chemist known for his works on carbon-coupling through the use of the atoms of the metal palladium to catalyze the bonding of carbons. This method was known as the Heck reaction. He was awarded the Nobel Laureate Prize in Chemistry last 2010 for his works that lead to a new way of innovation and inspiration to both young and old chemists. Heck was inspired to study science and in particular, chemistry from his interest in planting orchids when he was a child. As a teenager, he

    Analysis: Although only a simple water bottle rocket, it still applies to basic rocket theory. The simplest equation which applies is Tsiolkovsky's equation which describes a device that can apply acceleration to itself (a thrust) by expelling part of its mass with high speed and thereby move due to the conservation of momentum. In short the momentum which the rocket gains is that momentum which the water loses as it is expelled. The equation is: ∆v=V_e ln⁡(m_o/m_f ) Where: ∆v = change in velocity

    2.0 LITERATURE REVIEW 2.1 History background and action level Radon is a gaseous highly radioactive element discovered by English physicist Ernest Rutherford in 1899. The discovery is also credited to German physicist Friedrich Ernst Dorn in 1900. More specifically, Rutherford discovered radon's alpha radiation and Dorn discovered that radium was releasing a gas. Radon (chemical symbol Rn) is a naturally occurring radioactive gas found in soils, rock, and water throughout the U.S. It has numerous

    When Fire and Music Meets Physics we get the Pyro Board The Pyro board is a metal box with speakers attached to it and propane ran into it. There are holes strategically placed throughout the top depending on the boxes overall size and design for the flames. After the Pyro board is built it can be used to demonstrate sound waves. The Pyro board is an adaptation of the Rubens tube. The Rubens tube was invented in 1905 by Heinrich Ruben to demonstrate the relationship between sound waves and sound

    Introduction My essay is focused on chemical kinetics, which is only about 100 years old subfield of chemistry. Kinetics is topic, which investigates the speed of reaction. It is worth to investigate because it gives us knowledge about how reactions happen and about reaction mechanisms. As well as this, chemical kinetics can be used in many different areas: for instance, in pharmacology to work out how fast the drug dissolves or in food industry in order to understand food decomposition. This

    1 The hydrogen atom has one electron which can occur in 3s, 3p and 3d and since it is one electron it experiences the same nuclear charge (full nuclear charge). The effective nuclear charge felt by more than one electron in an orbital is not the same. This is due to electrons have the same charges, thus repel each other and shield the nucleus. Helium has two electrons; hence electrons repel each other and shield the nucleus. Additionally, the 1s orbital is close to the nucleus as compared to 3s

    Nuclear energy What is nuclear energy: Nuclear energy is a nuclear power that released by nuclear reaction to generate heat. the energy released. nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity by two ways. nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. But in nuclear fission, atoms are split into smaller atoms,
