http://quantumfreak.com An Educational Site About Quantum Mechanics and Theory of Relativity Sat, 06 Dec 2008 04:46:06 +0000 http://backend.userland.com/rss092 en According to the kinetic theory of gas, - Gases are composed of very small molecules and their number of molecules is very large. - These molecules are elastic. - They are negligible size compare to their container. - Their thermal motions are random. To begin, let's visualize a rectangular box with length L, areas of ... http://quantumfreak.com/derivation-of-pvnrt-the-equation-of-ideal-gas/ The idea that molecules are in constant motion was proposed by the kinentic theory of gases. The development of this theory in the 19th century are mostly based on the theory of atoms & molecules. Since there are no real experiments during that time, many leading physicists strongly opposed the idea. However, ... http://quantumfreak.com/motion-of-molecules/ Although the atomic theory proposed by John Dalton created a basic structure of the atom, the general idea of molecules was not cleared. In 1809, Frech chemist Joseph-Louis Gay-Lussac and others began doing numerous experiments with gases by measuring the amounts of gass that actually reacted. They found that two ... http://quantumfreak.com/concept-of-the-molecule/ The Idea of the atom were first proposed by the Greek philosophers Democritus and Leucippus around 400 B.C. At that time, there is absolutely no real evidence that support this proposal. Even after 20 centuries later, no experiment was strong enough to verify the existence of the atom.  In the 18th Century, the ... http://quantumfreak.com/atomic-proposal/ - Blackbody is a theoretical object that absorbs 100% radiation. - Carbon in graphite form absorbs all but about 3% of incoming radiation. - At a particular temperature the black body would emit the maximum amount of energy possible for that temperature. This value is known as blackbody radiation. - Maximum wavelength emitted ... http://quantumfreak.com/introduction-to-blackbody-radiation/ With classical physics, we are certain that we can determine the future by analyzing the data from the past and the present. However, the discovery of quantum mechanics shown that even with all necessary information, the future remains unknown. In the early 1900, four important events had revolutionized science and the ... http://quantumfreak.com/introduction-to-quantum-mechanics/ In the early 19th century, most phenomenons can be explained by classical (or Newtonian) mechanics. By the turn of the century, however, many anomalies instances spawned that can only be explained through Relativity and Quantum Mechanics. Relativity was discovered mainly to describe physics of very massive and very ... http://quantumfreak.com/history-of-quantum-mechanics-relativity/
