Nuclear Fission Nuclear Energy
603 wordsWhen dealing with the world's present sources of energy, the two most popular forms are nuclear and energy by fossil fuels. How long will these supplies last? Are they the most effective? Is it harmful to the environment? All of these questions must be addressed. Below is a description of how these sources produce energy. What exactly is nuclear energy? We talk about it all the time, but what is it? Nuclear energy is energy that is obtained by splitting the nuclei of atoms. The atoms of most ele...

Niels Bohr Model Of The Hydrogen Atom
365 wordsNiels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies ...

Carbon Dioxide Hydrogen Ions
1,424 wordsPhotosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6 CO 2 + 6 H 2 O + Light Energy = C 6 H 12 O 6 + 6 O 2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunli...

William Thomson (Lord Kelvin), referring to levitation as the problem of 'Mohamed's coffin, ' had this to say: 'It will orally be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble. ' Fields strong enough to lift...

World War Ii Franklin D Roosevelt
1,564 wordsOn the morning of August 6, 1945, the first Atomic Bomb in history was dropped on the Japanese city of Hiroshima. Three days later, a second bomb was dropped on Nagasaki. Soon after, on August 14, 1945, the Japanese abruptly surrendered, abandoning their ancient customs regarding honor in war. The fact that only two bombs were able to bring an entire country to its knees is a true testament to the awesome power they held. There is nothing in modern warfare that can compete with the devastating e...

Electron To Form Covalent Bond Bonds
446 wordsChemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, which concludes in an ionic ...

Atomic Weight Periodic Table
1,546 wordsAt first glance, nature appears to consist of countless numbers of very different materials. The world thus appears to be an extremely complex mixture of many different materials. But philosophers and scientists have long held another view of the world. They have found it difficult to believe that nature is really as complex as it appears to be. Instead, they have assumed that the many different materials we see result from the combination of a small number of fundamental substances called eleme...

University Of Cambridge Nobel Prize
1,240 wordsT 3 IBS Chemistry Historical Development of Atomic Structure The idea behind the atom goes back to the Ancient Greek society, where scientists believed that all matter was made of smaller, more fundamental particles called elements. They called these particles atoms, meaning not divisible. Then came the chemists and physicists of the 16 th and 17 th centuries who discovered various formulae of various salts and water, hence discovering the idea of a molecule. Then, in 1766 was born a man named J...

Coal Mines Carbon Dioxide
792 wordsMethane by Pamela The molecule, methane, is made up of one carbon and four hydrogen atoms making the compound CH 4. It is the second most important greenhouse gas. One molecule of methane is twenty times more efficient at absorbing infrared radiation than a molecule of carbon dioxide (CO 2). The amount of methane is increasing about 1 % a year, faster than any other greenhouse gas. Recently, the concentration is 1. 7 parts per million (ppm), which is nearly twice of what it was a few hundred of ...

Surface Of The Water Hydrogen Bonds
984 wordsWater is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earths thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one 1 (f...

Alpha Particles Natural Gas
520 wordsHow Helium Balloons Work There is something incredibly special about helium balloons! If you buy one at the circus or fair, you can hold its string and it will ride along above you. If you let go of the string it will fly away until you cannot see it anymore. If you have ever wondered why it flies away, the passages below can help you to figure out the mystery. Helium floatation Helium balloons work using exactly the same law of buoyancy. In this case, the helium balloon that you hold by a strin...

Stimulated Emission Nobel Prize
1,216 wordsThe Wonderful World of Lasers Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The laser has the unique ability to produce one specific color or wavelength of light, which can be varied in its intensity and pulse duration. The newest laser systems have become remarkably precise and selective, allowing treatment results and safety levels not previously available. All lasers contain...

Quot Lowell Fixed Stars
2,070 wordsThomas R. Edwards Imagistically the poem is built upon " enclosure" burial by snow, the subways vaults, the truss of the El, the interred Union dead, the sword in the groove foreshadowing the " mausoleum" of the last line. But these images suggest not only constraint and death but ceremony, formal rituals like burial, inauguration, or for that matter battle itself. The city observes the occasion: the subways drum, the girders " charge" as the poet passes them, the s...

Nuclear Power Plant Nuclear Fission
1,742 wordsNuclear energy-This is energy that binds together components of an atomic nucleus. This is made by the process of nuclear fission. Nuclear fission is produced when an atomic atom is split. The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate of the splitting of the nuclei at once which caus...
