Pauli exclusion principle

In this experiment, luminol, a compound that produces chemiluminescence when oxidized in the presence of a base by an oxidizing agent like hydrogen peroxide, was synthesized, and its presence was confirmed by observing chemiluminescence. Cheminluminescence is the process by which a photon is released when a reaction occurs, producing light. A similar process, bioluminescence is observed in nature when fireflies and jellyfish produce light. Chemiluminescence is identical to bioluminescence, except

The scientists of ancient times searched for the secrets of life, for the invisible and mysterious forces that pull the puppet strings of the world, not knowing that their true objective should have been the puppets themselves- the building blocks now known as atoms. The purported miracle of life is, in fact, far more miraculous when you bring atoms into the equation. To form a human being, trillions of drifting atoms must somehow find a way to assemble in a formation so specialized that it has never

cloud their masses have greatly decreased. The compression continues, making the star more and more dense. However there is a limit to the density of these stars as a result of their relatively small mass. This limit is connected to the Pauli exclusion principle which says that identical electrons cannot exist in the same energy state as another electron. This energy state relates to the position and momentum of the electron. As the star takes up less space, there is less opportunity for electrons

Advanced Engineering Materials MECH 5623 February 14, 2017 SUPERFLUIDS Joshua Hobson Oklahoma Christian University, Graduate School of Engineering Edmond, OK ABSTRACT “Superfluids” are fluids that have zero viscosity. This means that the fluid will flow with zero friction as well as leak through certain surfaces that are otherwise considered sealed. In addition, superfluids are also superconductors. The paper discusses liquid helium, its discovery, properties applications and limitations. INTRODUCTION

Absorption Spectrum of Conjugated Dyes Bashar Baraz Lab Partners: whole class Physical Chemistry II 3/22/2015 Abstract: The highly conjugated system of the cyanine dyes makes it a very good compound in the development of more efficient solar cells. In this experiment, the maximum wavelength was measured for nine dyes using a UV-Vis spectrum. The result that were obtained agreed with Kuhn’s model for the less polarizable end groups such as 3,3 '-diethyloxadicarbocyanine and 3,3 '-diethyloxatricarbocyanine

Postulates of Dalton’s Atomic Theory The main points of Dalton’s atomic theory, an explanation of the structure of matter in terms of different combinations of very small particles, are given by the following postulates: 1. All matter is composed of indivisible atoms. An atom is an extremely small particle of matter that retains its identity during chemical reactions. 2. An element is a type of matter composed of only one kind of atom, each atom of a given kind having the same properties. Mass

Adam Dadulak LA124 Magnets: Magneto’s Revenge Magnetism Magnetism is a class of physical phenomena mediated by magnetic fields. All materials are in some way influenced by a magnetic field. The force between any two charged particles depends on the magnitude of the charge on each and the distance that separates them. In addition to electrical forces, there is a force due to the motion of the charged particles known as the magnetic force. Magnetic Poles Magnetic forces exert on one another similarly

LIFE CYCLE OF A STAR Stars are formed in nebulae, interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries, dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released

Since the dawn of the man we have been wanderers and explorers, looking up at the night sky, studying the stars, and pondering the origin of them. How did we get here? Who are we? Why are we here? Why does anything exist? These are questions that have baffled us since we first looked to the stars, and still do continue to linger amongst us. Will we ever know the answer to these questions? This cannot be easily answered, for we uncover new mysteries every day, but with the uncovering of one mystery
