Electrical conductor

Discussion of the Results and the Scientific Explanation The purpose of this experiment was to identify an unknown compound and discover its properties by devising experimental designs that enable for its identification (Cooper, 2009). Fifteen possible compounds were given, and a series of qualitative tests were used to eliminate the different possibilities and identify the specific unknown compound. These tests included a solubility test, which determines whether the compound is soluble in…

To know what the invention really is, you need to know the man behind it all and because of that, I gave a brief history of Thomas Edison, the inventor of the light bulb. Well the first one that was practical to use at least, in my essay you will learn about how the light bulb came to become what it is today. I wrote the past of Edison life following up to his scientific discovery and how we use it to this day. You will learn how important lights really are to the world and why we should be…

Metals What is a metal? A metal is a substance, which have distinctive qualities of particular type. Metals usually are shiny, hard opaque and good conductors. In ancient Latin and Greek it has been written that Theophrastus and Pliny The Elder were the ones who crated metals by characterising the chemical and physical properties. Theophrastus is a Greek philosopher who lived during 371-287 B.C. Pliny the Elder during AD 23-79 was a Roman author, naturalist and naturalist philosopher. During…

The Nanotube Introduction: Nanotubes, specifically the carbon nanotubes are just one of the handful of structures engineers and scientist use today that fall in the nanoscale category. Structures in the nanoscale category are usually between 1-100 nanometers, which one nanometer is one-billionth the size of a meter. A confusing yet beneficial property found in materials at the nanoscale is a concept call quantum called quantum mechanics. In quantum mechanics the laws of classic or Newtonian…

Determining Percent Composition of Unknown Copper Ore Sample Iodine-thiosulfate Method: An Analytical Method The objective of this experiment is to eliminate all interfering species from a sample of unknown copper ore in order to later determine pure copper content. Copper ore can be found in a mineral that contains pure copper and other species that is mined and can later have copper extracted from them (Taher, 1999). To eliminate all interfering species, such as Iron, Arsenic, and…

His list of inventions includes the phonograph, vitascope (paved the way for the first silent motion pictures), dictaphone, storage battery, and mimeograph. His most prominent achievement would be inventing the first known practical incandescent electrical lightbulb and found a way to generate and distribute electricity. This lead to Edison founding a company that could help deliver this utility and this company would later become General Electric Corporation. However, Edison wasn’t the only…

ore (minerals) in the Earth’s crust(1). The ore is initially mined then goes through processes to recover copper(2). Copper is important as it many chemical and physical properties. Copper is a good conductor of electricity and is malleable (the ability to be bent) which is why copper is used in electrical wiring. It is also used in bronze and brass as an alloying agent(3). Chemists use a sequence of chemical reactions to obtain a desired product that cannot be obtained in a single reaction. In…

besides the experimenter. The real focus was on the teacher because the “learner” was an actor. The experiment was designed to study the effect of punishment on learning. The learner was conducted into a separate room strapped to fake miniature electrical chair to prevent excessive movement. The teacher is told to read a pair of sample words and the learner must recite them without any errors. If a mistake was made the teacher must send electric shock to the learner’s chair that ranges from 15-…

Foreword On September 22, 2016, you said you needed information on the Circuit Lab I had recently completed in order to present information to high school students. You need this information by October 4, 2016, in order to talk to students about circuits and increase their interest in technical subjects and the engineering profession on Shadow-an-Engineer-Day on October 17, 2016. For the Circuit Lab, I was asked to use concepts of Ohm’s Law and read/analyze circuit diagrams with common…
