  • Nuclear Fusion - 508 words
    Nuclear Fusion Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy for us to sustain life on earth. For energy production on earth, different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two light forms (isotopes) of Hydrogen - Deuterium and Tritium; eventually reactions involving just Deuterium or Deuterium and Helium may be used. A brief breakdown of the fuels used are as follows, Deuterium is a very abundant isotope of hydrogen and can be extracted from all forms of wat ...

  • Why Nuclear Fusion Is So Cool For A Fusion Reaction To Take Place, The Nuclei, Which Are Positively Charged, Must Have Enough - 1,186 words
    Why nuclear fusion is so cool....... For a fusion reaction to take place, the nuclei, which are positively charged, must have enough kinetic energy to overcome their electrostatic force of repulsion. This can occur either when one nucleus is accelerated to high energies by an accelerating device, or when the energies of both nuclei are raised by the application of very high temperature. The latter method, referred to the application of thermonuclear fusion, is the source of a lot of really cool energy. Enough energy is produced in thermonuclear fusion to suck the paint of 1 city block of houses and give all of the residents permanent orange Afros. The sun is a example of thermonuclear fusion ...

    ... be one of those wacky science thingys. Sort of like why inflammable and flammable mean the same thing. Who knows. Anyway, Magnetic-field configurations fall into two typed: open and closed. Wow, that was real obvious. In an open configuration, the charged particles, which are spiraling along magnetic field lines maintained by a solenoid, are reflected at each end of a cell by stronger magnetic fields. I have found in my research that if one used a 9-volt battery (preferably from a old smoke detector) the reaction takes place much more efficiently. In this simplest type of mirror machine, many particles that have most of their velocity parallel to the solenoidal magnetic field are not re ...

  • Air And Water - 412 words
    Air And Water A major transition in the modern energy age began in the 1970s, when the big nations industry started to grow up rapidly. The use of oil was very important and overnight, oil prices shot through the roof, and the trend of ever-cheaper, ever-more-plentiful energy sources were in need. Another player on the modern energy stage is nuclear power. An industry that didn't exist 40 years ago is now at a huge amount of production, producing 20 percent of the nation's electricity. Ironically, the industry is fading out. New orders ceased 20 years ago, and as aging plants reach the end of their lives, they are closing, one by one. All the non-renewable energy resources have positive and ...

  • Energy - 1,130 words
    Energy Energy is the ability to do work. The two different types of energy are kinetic and potential. Kinetic energy is energy in motion and potential energy is energy that is stored. Energy is measured in units which are BTU (British thermal unit) and a joule. The Law of Conservation of Energy states that energy can't be created or destroyed, but it can be changed in form. Heat is a form of energy that comes in different forms such as conduction, convection, and radiation. Conduction is when energy is passed directly from one item to another. Metals are excellent conductors of energy. Plastics or other materials aren't. These are called insulators. Convection is the movement of gases or liq ...

    ... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

  • Fusion: Our Futures Energy - 969 words
    Fusion: Our Future's Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more smaller nuclei by bombarding them with neutrons of low energy. It was discovered in the 1930's in an attempt to make transuranium elements (elements with atomic numbers greater than Uranium that do not ex ...

  • History Of Chemistry - 1,607 words
    History Of Chemistry History of Chemistry Introduction: Humans have always been very curios creatures. The have always wondered about what they are and why they are here. Our limited knowledge of the environment has always urged for new things to be discovered. The desire to understand the world better has made people search for rational answers, for principles and laws. For centuries people have tried to unlock the mysterious world that surrounds them. History: Because myths did not explain things well enough the Greeks began to ask questions about the world around them. They did this so thoroughly and so brilliantly that the era between 600 and 400 B.C. is called the golden age of philosop ...

  • How A Star Is Born - 1,174 words
    How A Star Is Born Birth of Stars Since my entire thesis for this paper is about how a star is born, I guess the first thing I should start out with is by telling you exactly what a star is. Stars are self-luminous gaseous spheres. They shine by generating their own energy and radiating it off into space. The stars' fuel for energy generation is the stuff they are made of -- hydrogen, helium, carbon, etc. -- which they burn by converting these elements into heavier elements. Nuclear fusion occurs, which is when the nuclei of atoms fuse into nuclei of heavier atoms. The energy given off by a star through nuclear burning heats its interior to many millions and, even in some cases to Pleiades S ...

  • Hydrogen Bomb - 821 words
    Hydrogen Bomb The Hydrogen Bomb The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release huge amounts of energy. The hydrogen bomb is about a thousand time more powerful than the atomic bomb, which produces a nuclear fission explosion almost a million times more powerful than that of a comparably sized bomb using conventional high explosives such as TNT. The atomic bomb was an essential first step towards the development of the hydrogen bomb, before the atomic bomb w2as developed by the United States during World War 2, there was no way to produce the extreme amounts of heat needed to initiate the ...

    Nuclear Weapons A major problem concerning the world today is the disposal of nuclear weapons. With the Cold War, we have seen a massive build up of nuclear weapons, and no, that we are no longer in a state of global warfare, what is to be done with them? As a result of the build-up in nuclear weapons during the cold war the world is now facing major environmental problems trying to deactivate them, and in addition major debate are occurring on the policies of disarmament and deterrence as solutions to this global problem. Countries are becoming more aware of the fact that their citizens do not want to have to worry about a nuclear attack or environmental effects of nuclear weapons testing. ...

  • Nuclear Weapons, Explosive Devices, Designed To Release Nuclear Energy On A Large Scale, Used Primarily In Military Applicati - 1,937 words
    Nuclear Weapons, explosive devices, designed to release nuclear energy on a large scale, used primarily in military applications. The first atomic bomb (or A-bomb), which was tested on July 16, 1945, at Alamogordo, New Mexico, represented a completely new type of artificial explosive. All explosives prior to that time derived their power from the rapid burning or decomposition of some chemical compound. Such chemical processes release only the energy of the outermost electrons in the atom. See Atom and Atomic Theory. Nuclear explosives, on the other hand, involve energy sources within the core, or nucleus, of the atom. The A-bomb gained its power from the splitting, or fission, of all the at ...

  • Nucleosynthesis - 1,314 words
    Nucleosynthesis The big bang which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The factories which make these elements are stars. Nucleosynthesis or the synthesis of nuclei, is the process by which stars (which start out consisting mostly of H and He) produce all other elements. The key is nuclear fusion, in which small nuclei are joined together to form a larger nucleus. (This ...

  • Our Solar System, The Sun And Its Planets Has Not Always Been There - 459 words
    Our Solar system, the sun and its planets has not always been there. It is nearly five billion years ago, and there is no solar system, no planets, moons, no sun. Instead there is a big cloud of dust and gas called a nebula. This cloud has been slowly twisting for more than 10 billion years, held together by its own gravity. Then a star explodes......WOW!! its a super nova.... The blast pushes the gases of our nebula together. That strengthens the gravitational pull of those gases even more and they begin to come together still more. The whole cloud begins to get smaller and as it does so, it swirls faster and faster, and grows smaller and smaller. Ok, dudes and dudettes, lets take a closer ...

  • Plasma - 563 words
    Plasma Matter consists of atoms held together by electromagnetic forces. How tight these bonds are, determines which of the four states: solid, liquid, gas and plasma, matter exists as. Plasma is only found naturally in the corona and cores of stars and in bolts of lightning. There are three classic states of matter: solid, liquid, and gas; however, plasma is considered by some scientists to be the fourth state of matter. The plasma state is not related to blood plasma, the most common usage of the word; rather, the term has been used in physics since around the 1920s to represent an ionized gas. Space plasma physics became an important scientific discipline in the early 1950s with the disco ...

  • Solar Energy And Its Social Consequences - 664 words
    Solar Energy and Its Social Consequences To understand the social consequences of solar energy, one must be aware of what solar energy is. Solar energy is a radiant energy produced in the sun as a result of nuclear fusion reactions. It is transmitted to the earth through space in quanta of energy called photons, which interact with the earths atmosphere and surface. The strength of solar radiation at the outer edge of the earths atmosphere when the earth is at its average distance from the sun is called the solar constant. The intensity of energy actually available at the earths surface is less than the solar constant because of the absorption and scattering of radiant energy as photons inte ...
