experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured

Theme: Resistance and Revolt Topic: The Sugar Revolution Were the changes that were brought to the West Indies as a result of the sugar revolution beneficial or detrimental to the development of the West Indies? The period 1650 to 1823 was referred to as the sugar era‚ during that time sugar cane was the most important and profitable crop that was grown in the West Indies. Most planters turned to this crop as they found out that the changes of the sugar revolution were very beneficial to them

| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law

Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C.‚ Thales‚ a Greek philosopher and scientist‚ observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered‚ in effect‚ static electricity. William Gilbert‚ an English scientist in the sixteenth century‚ found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other‚ they were able to attract each other

Unit 4 Assignment 1 Copper vs. Fiber Paper Copper wire is found in most household electric or electrical related devices. One advantage of copper wire is its conductivity. Copper wire is second only to silver wire in level of conductivity meaning it will accept a current more so than almost any other type of wire. Copper wire is also heat resistant and can handle high levels of charge without many issues with overloading the wire. Copper in itself is also resistant to corrosion. This helps
