Nuclear energy is created in nuclear power plants‚ specifically designed to withstand the process of nuclear fission. At a nuclear power plant‚ nuclear fission occurs inside the reactor containing a core with uranium pellets. As the atoms break open‚ neutrons are released. These then bump and break open other uranium atoms. This continuous process of breaking and bumping is called a chain reaction. When the uranium nuclei split‚ heat is released‚ boiling water into steam which drives large turbine blades

1) What is the difference between pseudoscience and scientific evidence? Pseudoscience: anything being presented‚ as scientific but is not. Usually characterized by exaggerations‚ UN falsifiable claims‚ and anecdotes. Scientific Evidence: A process of inquiry followed by a body of knowledge. 2) Describe 3 main types of scientific inquiry: 3 types of scientific inquiry. Descriptive: what’s out there? Observing‚ no manipulations of variables Comparative: Seeks to describe relationships and correlations

Ernest Rutherford Born on August 30th‚ 1871 in New Zealand‚ Ernest Rutherford accomplished to be one of many successful chemists throughout the world in the 19th and the 20th centuries. With his brilliant experiments he explained the puzzling problem of radioactivity and the sudden breakdown of atoms. In addition‚ he determined the structure of the atom and was first to ever split it. Rutherford’s great mind triggered innovations of new technology such as the smoke detector that saves many

Manganese. The symbol for manganese is Mn. It is number 25 on the periodic table. That means it has 25 protons and electrons even on mars or anywhere you go it will have the same protons and electrons. The atomic number would also be 25. It has 30 neutrons also in in the nucleus. The melting point for Manganese would be 1519 K (1246°C or 2275°F). The boiling point would be 1519 K (1246°C or 2275°F) according to http://education.jlab.org/. It also could be 1245.0 °C (1518.15 K‚ 2273.0 °F) and 1962

Atoms make up everything around us‚ including ourselves. They consist of protons which give off a positive charge‚ electrons which give off a negative charge and neutrons which have no charge. In an atom there are the same amount of protons as there are electrons. If there weren’t it would cause the atom to behave differently. Atoms have layers around them called shells which contain electrons. Each shell can only hold a certain amount of electrons. Molecules can be multiple atoms of the same element

such as Uranium‚ the impact of a particle on the nucleus loosens its binding force. The impact causes the nucleus to break apart into pieces‚ also known as fission fragments. These pieces contain a nucleus with approximately half the protons and neutrons of the original nucleus; they fly at very high speeds and possess high amounts of energy. This energy is released in many forms‚ but most energy released by

process called nuclear fission. Though there are many arguments in favour and against both‚ nuclear fission currently holds the upper hand as a nuclear fusion reactor is yet to be formed. Nuclear fission occurs when a stable isotope is hit by a neutron causing the isotope to absorb it‚ making it unstable and splitting it apart releasing huge amounts of energy. Nuclear fission is currently used for nuclear weapons and nuclear reactors‚ examples of isotopes that can undergo the process are Uranium235

Large Hadron Collider: Will it get a Positive or Negative charge? Executive Summary I’ve come to learn through extensive research on the Large Hadron Collider that there are viewpoints‚ which seem to be set to a stalemate. First the pro benefits to the LHC include ideas such as the possibility to increase the energy efficiency of viewing particle reactions by a factor of four. We may also look at how it examines such issues as: the flow of "interlaced" knowledge between specialist teams; the
