Non-Renewable Energy Resources This Project will be in two Parts. The first part is about Non-renewable energy. Non-renewable energy is a resource that will some day we will run out of. Non-renewable energy is a resource that will some day we will run out of. The second part is on Renewable energy. Renewable energy is a resource that we will never run out of because it is continually being replaced. The sun is the source of all our energy resources. The sun’s energy reaches Earth and

Nuclear Power Debate Year 11 Physics Gurjyot Singh Australia currently has no nuclear facilities generating electricity‚ which is forcing the Australian Government to look towards nuclear energy as a great alternative. Nuclear energy is a growing controversial topic in Australia; because the demands of utilizing electricity are increasing rapidly. According to a recent study‚ Australia has 23% of the world’s uranium deposits and is the second largest producer of uranium

particles called protons‚ electrons and neutrons. Protons carry a positive electrical charge‚ electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom‚ called the nucleus‚ and the electrons ’orbit’ the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles

nucleus of an atom. Splitting an atom was caused by neutrons firing through one atom and then that atom’s neutrons shoot off into other atoms‚ starting a chain reaction. In October of 1934‚ Enrico Fermi‚ and Italian physicist‚ discovered how to successfully split an atom. Soon after‚ this led the atomic bomb to use the same techniques of nuclear fission. Nuclear fuel goes through fission when struck by free neutrons and then generates neutrons when it breaks apart. Only U-235 uranium atoms‚ a nuclear

whole-number ratios to form compounds (see below)‚ in a chemical reaction‚ atoms are separated‚ combined‚ or rearranged. Whole-number ratios: No halfsies. But he was wrong about atoms being indivisible (that’s how we know about protons and neutrons and electrons and the other subatomic particles). And how atoms of the same element have identical properties: atoms of an element may have slightly different masses‚ e.g: ISOTOPES. You can see an atom using the scanning tunneling microscope.

That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however‚ they are just a little different from every other atom of the same element. Most of the carbon atoms in the universe are Carbon-12‚ with 6 neutrons. A small percentage of carbon atoms are Carbon-13‚ with 7 neutrons‚ and an even smaller percentage are Carbon-14 and have 8 neutrons. Carbon-13 and Carbon-14 are isotopes of carbon. Atomic mass

maintains the properties of that element. • Chemical Group – the set of elements in the same column of the periodic table. These elements have similar physical and chemical properties. • Isotope – An isotope of an element has different number of neutrons. • Radioisotopes – Some isotopes are unstable‚ which means that the nucleus has a tendency to break apart and eject particles. Atoms that have unstable nucleus are called radioisotopes. • Subatomic particles – the particles of which an atom is

How did the universe originate and evolve to produce the galaxies‚ stars‚ and planets we see today? How did we get here? In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky‚ we must understand how stars‚ galaxies and planets are formed. There are many questions associated with the creation and evolution of the major

The evolution of the early universe was the aftermath of the big bang. The early stages of the universe evolved which lead to the creation of matter and the separation of what is now known as the four fundamental particles of the universe. The creation of matter in the early universe was aided by the four fundamental forces‚ the strong force‚ the weak force‚ the electromagnetic force and the force of gravity. The standard model includes the three of the four fundamental forces excluding gravity
