Over the past half century our world has become more modernized than ever thought possible. We have innovative things to make our lives quicker and more efficient including DVDs‚ the IPod‚ and the Internet. This technology has become integrated into our society and even in a way part of our lives. It has also led to increased manufacturing and production and in turn increased the CO2 output by man kind. However‚ is this increase substantial enough to cause a change in the Earth’s climate? Scientists

1. What was phlogiston? Based on what theoretical and experimental bases did Lavoisier reject it? (68) Phlogiston is a substance that was once believed to be in all combustible materials. The phlogiston theory originated in Ancient Greek around 1667 by Johann Joachim Becher‚ a German physician who pursued alchemy. The purpose of this theory was to help explain why materials turned to ash after burning and why the break down of metals through rusting. The phlogiston theory states that flammable

Joseph John "J. J." Thomson In 1897 Thomson showed that cathode rays were composed of a previously unknown negatively charged particle‚ and thus he is credited with the discovery and identification of the electron; and‚ in a broader sense‚ with the discovery of the first subatomic particle. Thomson is also credited with finding the first evidence for isotopes of a stable (non-radioactive) element in 1913‚ as part of his exploration into the composition of canal rays (positive ions). He invented

The History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity

ELECTRICITY MR.ROBINSON Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects‚ such as lightning‚ static electricity‚ electromagnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity‚ charges produce electromagnetic fields which act
